If you are using JWT SSO in Sisense, the SSO might stop working after upgrading to version 6.7 and up.

The reason for that could be a missing "typ": "JWT" attribute in the JWT token's header.

To check if the header attribute is missing, retrieve the JWT token generated by your system and plug it into a JWT online debugger such as jwt.io.

Check the decoded header of the token to see whether the "typ": "JWT" exists or not.

For example:

Solution

 Modify you SSO script to explicitly include the "typ": "JWT" in the generated JWT token.
