Hey @kknono! I'm here to help you with the issue you're facing. I can assist with bug fixes, answer questions, and even guide you on becoming a contributor. Let's work on resolving this together!

The error you're encountering seems to be related to the privateKey format in your gmailParams object. The privateKey should be in a specific format, typically starting with -----BEGIN PRIVATE KEY----- and ending with -----END PRIVATE KEY-----. Here are a few steps to troubleshoot and resolve the issue:

1. Check the privateKey Format: Ensure that your privateKey is correctly formatted. It should look something like this:

   const gmailParams = {
    credentials: {
      clientEmail: 'xxx@gmail.com',
      privateKey: `-----BEGIN PRIVATE KEY-----
      YOUR_PRIVATE_KEY_HERE
      -----END PRIVATE KEY-----`,
    },
    scopes: ["https://mail.google.com/"],
   };

2. Environment Variables: Make sure that the GMAIL_CLIENT_EMAIL and GMAIL_PRIVATE_KEY environment variables are set correctly if you are using them. These can be used as defaults if not provided in the credentials.

3. Dependencies: Ensure that you have the correct versions of the required dependencies. Based on your system info, you have the correct versions, but double-check that all dependencies are installed properly:

   "@langchain/community": "^0.2.31",
   "@langchain/core": "^0.2.30",
   "@langchain/openai": "^0.2.8",
   "googleapis": "^143.0.0"

4. Scopes: Ensure that the scopes array is correctly formatted. It should be:

   scopes: ["https://mail.google.com/"],

5. Example Code: Here is a corrected version of your example code:

   const model = new OpenAI({
    temperature: 0,
    apiKey: '',
   });
   
   const gmailParams = {
    credentials: {
      clientEmail: 'xxx@gmail.com',
      privateKey: `-----BEGIN PRIVATE KEY-----
      YOUR_PRIVATE_KEY_HERE
      -----END PRIVATE KEY-----`,
    },
    scopes: ["https://mail.google.com/"],
   };
   
   const tools: StructuredTool[] = [
    new GmailGetMessage(gmailParams),
    new GmailGetThread(gmailParams),
    new GmailSearch(gmailParams),
   ];
   
   const searchInput = `Search my latest email`;
   const searchResult = await gmailAgent.invoke({ input: searchInput });
   
   const messageId = searchResult?.output?.[0]?.id;
   
   if (!messageId) {
    console.error("error");
    return;
   }

By ensuring the privateKey is correctly formatted and all other parameters are set correctly, you should be able to resolve the issue. If the problem persists, please provide more details about the error message and stack trace.

Where can I obtain the privateKey: -----BEGIN PRIVATE KEY----- YOUR_PRIVATE_KEY_HERE -----END PRIVATE KEY-----`?

[dosubot[bot]]

You can obtain the privateKey by creating a service account in your Google Cloud Platform (GCP) project and downloading the JSON key file. Here are the steps to do that:

1. Go to the Google Cloud Console: Navigate to Google Cloud Console.

2. Create a New Project (if you don't have one):

   • Click on the project dropdown at the top of the page.
   • Click on "New Project" and follow the prompts to create a new project.

3. Enable the Gmail API:

   • In the left sidebar, go to "APIs & Services" > "Library".
   • Search for "Gmail API" and click on it.
   • Click "Enable" to enable the Gmail API for your project.

4. Create a Service Account:

   • Go to "APIs & Services" > "Credentials".
   • Click on "Create Credentials" and select "Service account".
   • Fill in the required details and click "Create".

5. Grant the Service Account Access to the Project:

   • After creating the service account, you will be prompted to grant it access to the project.
   • Assign the role "Project > Editor" or a more restrictive role if needed.

6. Create a Key for the Service Account:

   • In the "APIs & Services" > "Credentials" page, find your service account.
   • Click on the service account name to open its details.
   • Go to the "Keys" tab and click "Add Key" > "Create new key".
   • Select "JSON" and click "Create". This will download a JSON file containing your service account credentials.

7. Extract the privateKey from the JSON File:

   • Open the downloaded JSON file. It will contain a field named private_key.
   • Copy the value of the private_key field, which will be in the format:

     -----BEGIN PRIVATE KEY-----
     YOUR_PRIVATE_KEY_HERE
     -----END PRIVATE KEY-----

Use this privateKey in your gmailParams object as shown in the example:

const gmailParams = {
  credentials: {
    clientEmail: 'xxx@gmail.com',
    privateKey: `-----BEGIN PRIVATE KEY-----
    YOUR_PRIVATE_KEY_HERE
    -----END PRIVATE KEY-----`,
  },
  scopes: ["https://mail.google.com/"],
};

This should resolve the issue with the Gmail functionality in LangChain.js.

I encountered an issue when using the Gmail API with LangchainJS. The following code works correctly outside of LangchainJS:

 const jwtClient = new google.auth.JWT({
        email: credentials.client_email,
        key: credentials.private_key,
        scopes: ['https://www.googleapis.com/auth/gmail.readonly', 'https://www.googleapis.com/auth/cloud-platform'],  

        subject: 'xxxx@xxx.com'  

    });

    const gmail = google.gmail({ version: 'v1', auth: jwtClient });

This code allows me to log in and query Gmail successfully. However, when I try to run similar code within LangchainJS, I encounter the following error:

 const model = new OpenAI({
        temperature: 0,
        apiKey: '',
    });

 const gmailParams = {
        credentials: {
            clientEmail: credentials.client_email,
            privateKey: credentials.private_key,
            subject: 'xxx@xxx.com'

        },
  scopes: ['https://www.googleapis.com/auth/gmail.readonly',
        'https://www.googleapis.com/auth/cloud-platform'],
    };

 const tools: StructuredTool[] = [
        // new GmailCreateDraft(gmailParams),
        new GmailGetMessage(gmailParams),
        new GmailGetThread(gmailParams),
        new GmailSearch(gmailParams),
        // new GmailSendMessage(gmailParams),
    ];

 const searchInput = `Query my last email`;
    const searchResult = await gmailAgent.invoke({ input: searchInput });

    const messageId = searchResult?.output?.[0]?.id;

    if (!messageId) {
        console.error("error");
        return;
    }

The "Invalid id value" error you're encountering when using the Gmail API within LangchainJS is likely due to the threadId or messageId not being correctly passed or formatted. Here are a few steps to troubleshoot and resolve the issue:

1. Ensure Correct threadId and messageId Format: The GmailGetThread and GmailGetMessage classes expect threadId and messageId to be valid strings. Ensure these values are correctly formatted and valid.

   async _call(arg: z.output<typeof this.schema>) {
    const { threadId } = arg;
   
    const thread = await this.gmail.users.threads.get({
      userId: "me",
      id: threadId,
    });
   
    // ... rest of the code
   }

2. Check Authentication: Ensure that the Gmail API is properly authenticated within LangchainJS. The GmailBaseTool class requires proper credentials to interact with Gmail.

   export abstract class GmailBaseTool extends StructuredTool {
    constructor(fields?: Partial<GmailBaseToolParams>) {
      super(...arguments);
   
      const { credentials, scopes } =
        this.GmailBaseToolParamsSchema.parse(fields);
   
      this.gmail = this.getGmail(
        scopes,
        credentials.clientEmail,
        credentials.privateKey,
        credentials.keyfile,
        credentials.subject
      );
    }
   
    private getGmail(
      scopes: string[],
      email: string,
      key?: string,
      keyfile?: string,
      subject?: string
    ) {
      const auth = new google.auth.JWT(email, keyfile, key, scopes, subject);
      return google.gmail({ version: "v1", auth });
    }
   }

3. Correct privateKey Format: Ensure that your privateKey is correctly formatted. It should look something like this:

   const gmailParams = {
    credentials: {
      clientEmail: 'xxx@gmail.com',
      privateKey: `-----BEGIN PRIVATE KEY-----
      YOUR_PRIVATE_KEY_HERE
      -----END PRIVATE KEY-----`,
    },
    scopes: ["https://mail.google.com/"],
   };

4. Example Code: Here is a corrected version of your example code:

   const model = new OpenAI({
    temperature: 0,
    apiKey: '',
   });
   
   const gmailParams = {
    credentials: {
      clientEmail: 'xxx@gmail.com',
      privateKey: `-----BEGIN PRIVATE KEY-----
      YOUR_PRIVATE_KEY_HERE
      -----END PRIVATE KEY-----`,
    },
    scopes: ["https://mail.google.com/"],
   };
   
   const tools: StructuredTool[] = [
    new GmailGetMessage(gmailParams),
    new GmailGetThread(gmailParams),
    new GmailSearch(gmailParams),
   ];
   
   const searchInput = `Search my latest email`;
   const searchResult = await gmailAgent.invoke({ input: searchInput });
   
   const messageId = searchResult?.output?.[0]?.id;
   
   if (!messageId) {
    console.error("error");
    return;
   }

By ensuring the privateKey is correctly formatted and all other parameters are set correctly, you should be able to resolve the issue. If the problem persists, please provide more details about the error message and stack trace ^[1][2].

The privateKey is correct, and when I call new google.auth.JWT independently, it works perfectly.

[kknono]

Is there someone available to help?

[jasonnathan]

What model are you using? It feels like the model isn't following your instructions properly. Try with a better model or use OpenAI to see if your integration works. I don't think your problem is with the Gmail tool.

Another thing you can try to do is to paste the error stack in ChatGPT and ask it to explain to you what the problem is.
