Oauth2 replies 400 with no useful error message

Hi @juliofarah,

That's correct. The new version of our node library does not have an internal helper function for OAuth-2 based authentication. We have had some issues with this internal helper function in the past with some of our other libraries so we didn't implement it for the new client library versions. Developers can use an external OAuth 2.0 library like passport-oauth2
to help them implement OAuth 2.0 for their app server. Or they could use a request library like axios and implement OAuth through there like you are. That being said, I'll take a note of this and bring this up with our team to see if we can add this feature back into a future update of our node library.

As for your issue with OAuth. I think you might want to catch the error from axios to access the error Asana is throwing back in the response. For example instead of:

    const tokenResponse = await axios.post(`https://app.asana.com/-/oauth_token`, body, config);

You might want to try:

  let tokenResponse = null;
  try {
      tokenResponse = await axios
      .post("https://app.asana.com/-/oauth_token", body, config);
  } catch (err) {
      // Print Asana error
      console.log(err.response.data.error_description)
  }

Here are some of my guesses to what your error might be:

1. The redirect URL you provided in your code does not match the Redirect URLs you specified in the developer console (https://app.asana.com/0/my-apps/<YOUR_APP_ID>/oauth) (See #2: https://developers.asana.com/docs/oauth#register-an-application)
2. Edit your manage distribution settings to allow access to your target workspace or any workspace (See How to share your app)

Let me know if you are able to see the error message from Asana
