Zoom Video SDK - Jwt auth fails

Question

We have implemented an API within our backend that generates a jwt token according to the specifications indicated in the documentation. When we pass the token to the VideoSDK web ui-toolkit, in some cases we get the error:

zoomsdkjsonpcallback1({ "status": false, "errorCode": 124, "errorMessage": "Verify JWT Failed: The token was expected to have 3 parts, but got 1." })

We have already verified that the token contains all the necessary fields in the payload.

Sometimes a token that fails on some subsequent attempt works fine.

Any suggestions?

Problem solved!

It's a problem related to signature final encoding, so by using:

Base64.getUrlEncoder().encodeToString(signedBytes);

instead of

Base64.getEncoder().encodeToString(signedBytes);

My bad.

authentication works
