How can I resolve the "InvalidAuthenticationToken" error due to an improperly formatted JWT with too many dots when calling the graph api after sme time it start working normally

Hi everyone,

I'm encountering an issue with fetching chats from [API/Service Name]. When I attempt to call the API, I receive the following for message

Error fetching chats:

It seems that the JWT token is not correctly formatted, with more dots than allowed. This issue seems to resolve itself intermittently. Note that it start working fine after the some time it start working normally

Can someone help me understand why this error occurs and how to fix it? Any insights on ensuring the token is correctly formatted or any best practices for handling JWT tokens would be greatly appreciated.

Thank you!

Hi @LOKESH K

Thank you for posting this in Microsoft Q&A.

The error you're encountering is likely due to the JWT token being malformed or not confirming to the expected format. A valid JWT token should have three parts: header, payload, and signature, separated by dots (.).

Here's an example of a correctly formatted JWT token:

eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaGFuIjoiMjMwfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

To fix this issue, you should ensure that the JWT token is generated correctly and confirms to the expected format.

1.Check how the JWT token is being generated and ensure that it's done correctly. Make sure that the header, payload, and signature are separated by dots (.) and that the token is not malformed.

2.Verify that the token format is correct and conforms to the expected format. You can use online tools like jwt.io to decode and verify the token.

3.Implement error handling mechanisms to catch and handle token-related errors. This will help you identify and fix issues with the token more efficiently.

Hope this helps. Do let us know if you any further queries.

Thanks,
