Error building Component Astra DB: Error initializing AstraDBVectorStore: {"errors":[{"message":"Request invalid: field 'command.name' value `null` not valid. Problem: must not be null.","errorCode":"COMMAND_FIELD_INVALID"}]} #3393

Bug Description

This error is happening when I export the flow JSON trying to run it on my application.

Reproduction

from langflow.load import run_flow_from_json TWEAKS = { "ChatInput-UuJgn": {}, "AstraVectorStoreComponent-2mwWS": {}, "ParseData-M3W6Z": {}, "Prompt-dt6pd": {}, "ChatOutput-R5l9b": {}, "SplitText-PbqQD": {}, "File-N0Za6": {}, "OpenAIModel-LYQTz": {}, "Memory-u45lJ": {}, "OpenAIEmbeddings-ZAXxT": {} }

result = run_flow_from_json(flow="Vector_Store_RAG.json", input_value="message", fallback_to_env_vars=True, # False by default tweaks=TWEAKS)

Expected behavior

I would expect to run the flow in my Django external application.

Who can help?

@Nkurayijahubert Hello there! I'm here to help you with any bugs, questions, or contributions. Let's get to the bottom of this together.

To resolve the error "Request invalid: field 'command.name' value null not valid. Problem: must not be null." when trying to build a component for Astra DB, you need to ensure that the command.name field is not null. This typically means that the name field for the component is missing or not set in your flow JSON.

Here is an example of how you can set the name field for the component:

{
  "template": {
    "_type": "Component",
    "name": "your_component_name",  // Ensure this field is set
    "chunk_size": {
      "advanced": true,
      "display_name": "Chunk Size",
      "dynamic": false,
      "info": "",
      "list": false,
      "name": "chunk_size",
      "placeholder": "",
      "required": false,
      "show": true,
      "title_case": false,
      "type": "int",
      "value": 1000
    },
    "client": {
      "advanced": true,
      "display_name": "Client",
      "dynamic": false,
      "info": "",
      "input_types": [
        "Message",
        "str"
      ],
      "list": false,
      "load_from_db": false,
      "name": "client",
      "placeholder": "",
      "required": false,
      "show": true,
      "title_case": false,
      "type": "str",
      "value": ""
    },
    // ... other fields ...
  }
}

Make sure to replace "your_component_name" with the actual name you want to give to your component. This should resolve the error by ensuring that the command.name field is not null [1].

Nkurayijahubert commented 2 months ago

@dosu do I have to add it manually?

dosubot[bot] commented 2 months ago

Yes, you will need to manually add the name field to your flow JSON for the Astra DB component. Ensure that each component in your JSON has a valid name field set to avoid the error. If you have multiple components, verify that each one has a unique and non-null name field. This should resolve the issue you're encountering.

To continue talking to Dosu, mention @dosu.

Nkurayijahubert commented 2 months ago

@dosu There many places with "template": {}

dosubot[bot] commented 2 months ago

To ensure the command.name field is not null, you need to add the name field within the template object of the specific component causing the issue. For the Astra DB component, it should look something like this:

{
  "template": {
    "_type": "Component",
    "name": "AstraDBComponent",  // Add this line
    "chunk_size": {
      "advanced": true,
      "display_name": "Chunk Size",
      "dynamic": false,
      "info": "",
      "list": false,
      "name": "chunk_size",
      "placeholder": "",
      "required": false,
      "show": true,
      "title_case": false,
      "type": "int",
      "value": 1000
    },
    "client": {
      "advanced": true,
      "display_name": "Client",
      "dynamic": false,
      "info": "",
      "input_types": [
        "Message",
        "str"
      ],
      "list": false,
      "load_from_db": false,
      "name": "client",
      "placeholder": "",
      "required": false,
      "show": true,
      "title_case": false,
      "type": "str",
      "value": ""
    }
    // ... other fields ...
  }
}

Make sure to add the "name": "AstraDBComponent" line within the template object of the Astra DB component. If you have multiple components, ensure each one has a unique and non-null name field within their respective template objects [1].

dosubot[bot] commented 2 months ago

Ensure that the name field is correctly set for each component in your flow JSON. Here is a more detailed example for the Astra DB component:

{
  "template": {
    "_type": "Component",
    "name": "AstraDBComponent",  // Ensure this field is set

Ensure that the name field is set to a non-null value for the Astra DB component and any other components in your JSON. This should resolve the error [1].

Hi @Nkurayijahubert, can you please share the exact steps you took?

I just tested that I was able to export the Vector Store RAG example and run it locally on my machine via the run_flow_from_json function. Attached is the json I used, and the code to run it. Plmk if that works for you, then we can figure out if anything is different in your environment.

from langflow.load import run_flow_from_json
TWEAKS = {
  "ChatInput-iaJtf": {},
  "AstraVectorStoreComponent-rd8LL": {
      "token": "<insert token>",
      "api_endpoint": "<insert endpoint>"
      },
  "ParseData-aybR0": {},
  "Prompt-jCJmL": {},
  "ChatOutput-JP4os": {},
  "SplitText-CQxrN": {},
  "File-IlhlA": {},
  "AstraVectorStoreComponent-7hUKp": {},
  "OpenAIEmbeddings-l7Jz2": {},
  "OpenAIEmbeddings-6YrUm": {},
  "OpenAIModel-W43IT": {}
}
# and I just exported `OPENAI_API_KEY` in the terminal I was running this from

result = run_flow_from_json(flow="test_rag.json",
                            input_value="message",
                            fallback_to_env_vars=True, # False by default
                            tweaks=TWEAKS)

print(result)

Nkurayijahubert commented 2 months ago

Hi @jordanrfrazier these are the steps I am taking:

flow_file = "vector_store.json"

TWEAKS = { "File-x63LT": {}, "SplitText-fRVmN": {}, "OpenAIEmbeddings-rU5oN": { "openai_api_key": os.getenv("OPENAI_API_KEY"), }, "AstraDB-305Eo": { "api_endpoint": os.getenv("ASTRA_DB_API_ENDPOINT"), "token": os.getenv("ASTRA_DB_APPLICATION_TOKEN"), }, "ChatInput-bLV8x": {}, "ParseData-7oE65": {}, "Prompt-z6UsK": {}, "Memory-re2mi": {}, "OpenAIModel-ul65C": { "api_key": os.getenv("OPENAI_API_KEY"), }, "ChatOutput-4YOYF": {}, }

flow = run_flow_from_json(flow=flow_file, input_value="Hello, what is the capital of France?", fallback_to_env_vars=True, # False by default tweaks=TWEAKS)

jordanrfrazier commented 2 months ago

@Nkurayijahubert can you please attach your flow json file here, and I'll try running and debugging on my end tomorrow

Nkurayijahubert commented 2 months ago

Here it is @jordanrfrazier

jordanrfrazier commented 2 months ago

Hi @Nkurayijahubert sorry for the late response. I was able to download and run your given JSON file, though I did re-upload the flow into a locally running langflow in order to verify the ID's of the components were correct for the TWEAKS.

Can you please try to
