@Rishabh-malhotraa I set up the project again and I am now able to fetch the problems from codeforces and leetcode problems list is also available, messaging feature also seems fine but the code is not getting compiled. Here is a screenshot of the console errors -

P.S - I haven't created any .env files this time as I have followed these instructions.

[Rishabh-malhotraa]

You should not need to create a .env file as config.keys add default values if .env file is not created, you would require to create a .env file if you need to add your oauth token credentials etc.

• You need to get your JDOODLE api keys to execute code(a free account is limited to 200 executions per day).

(For adding jdoodle credentials you need to create and .env file)

JDOODLE_CLIENTID=get_your_key
JDOOLDE_CLIENTSECRET=get_your_key

• Change export const JDOODLE_URL = process.env.JDOODLE_URL || "https://api.jdoodle.com/v1/execute"; to export const JDOODLE_URL = process.env.JDOODLE_URL || "https://api.jdoodle.com/v1"; in config.keys I fixed this issue you can just pull it from main

[prayutsu]

@Rishabh-malhotraa I made the changes you mentioned -

1. Created a .env file
2. Put JDOODLE_SECRETS in it.
3. Updated JDOODLE_URL (took a pull from main).

But the app is getting crashed when I am clicking on run code button.

Why it is returning an unauthorized status code?

[Rishabh-malhotraa]

Why it is returning an unauthorized status code?

I you are getting unauthorized, that means your tokens are incorrect, can you recheck your tokens, you require two of them

[prayutsu]

@Rishabh-malhotraa I doubted same, and I therefore checked the secrets 4-5 times.

My .env file

JDOODLE_CLIENTID=832e180ceafc5633a65a66e23fb22ad4
JDOOLDE_CLIENTSECRET=e310c26040828fdfa6eb3958cbd205310095937f2d552ea0e3e37b12a0ea2e2b

This is what I get from JDOODLE credentials tab - Client ID 832e180ceafc5633a65a66e23fb22ad4 Client Secret e310c26040828fdfa6eb3958cbd205310095937f2d552ea0e3e37b12a0ea2e2b

I believe that they both are the same.

I also tried refreshing credentials and getting a new client secret but the error remains the same.

[Rishabh-malhotraa]

I think it's your still your credential keys issue you can try getting your keys from a different account

for now, you can use these keys, but I'll refresh them tomorrow so you would not be able to use them after tomorrow, so maybe try getting the keys from a different account.

JDOODLE_CLIENTID=da358ecadea106b681e17e6dd1194863
JDOOLDE_CLIENTSECRET=7b69d6ce85668cb6fe5dbd61d37433bf3ffe31c14fed906833faad7e2593f5ca

[prayutsu]

Unfortunately, I am getting the same error even if I tried the credentials provided above. But the status code is 404 this time.

Upon trying again, it resulted in a 401 status code again.

[Rishabh-malhotraa]

you need to restart the server once you update the env file

Actually, I did restart the server several times. I took a few snapshots of the console. Maybe it can help to identify the problem.

Also, one more thing to note is that if I click run code on empty code, it doesn't throw any error. That means -

We are reaching out to some part of the the /execute endpoint -

router.post("/execute", async (req, res) => {
  const { script, language, stdin } = req.body;
  if (!language || !script) {
    return res.status(200).json({
      message: "Code should not be empty and Language undefined",
    });
  }

  const response = await axios({
    method: "POST",
    url: `${JDOODLE_URL}/execute`,
    data: {
      script: script,
      stdin: stdin,
      language: getLanguage[language],
      versionIndex: getLanguageVersion[language],
      clientId: JDOODLE.clientID,
      clientSecret: JDOODLE.clientSecret,
    },
    responseType: "json",
  });
  res.json(response.data);
});

@Rishabh-malhotraa Did you get a chance to investigate further?

[Rishabh-malhotraa]

Can you try running on incognito and maybe do a reinstall of Caucus with latest commit(don't add any env file in the clean install as the config file contains the credentials now)

This finally worked. Thanks, @Rishabh-malhotraa for helping me set up the project.
