issue with jwt when joining call in 8x8 meet

Question

I’m currently facing an issue with the JWT token I generated for joining calls using the 8x8 API. While the static JWT token from the portal works perfectly, the one I create programmatically results in the following error: "You cannot join the call."

Here are some details about my implementation:

Claims Verification: I’ve verified that the JWT contains all necessary claims, including exp, iss, and sub. Expiration: I ensure that the token is not expired. Audience Claim: I’ve checked that the aud claim is correctly set, as required by the API. Permissions: I’ve confirmed that the token has the required permissions for joining calls. Signing: I’m using the correct private key and signing algorithm. Additionally, I can successfully decrypt the generated JWT on jwt.io and see all the expected data.

Has anyone else encountered this issue or have tips on what I might be missing? Any guidance would be greatly appreciated!

Note: I’ve tried a solution (included in my GitHub repository) but it’s not working. Interestingly, when I use the static token generated from the 8x8 portal, it works perfectly fine.

Thank you!
