JWT token not working after upgrade - [Linux] and [Windows]
Step-by-Step Guide
- Confirm the Issue
After upgrading your Sisense, your JWT SSO login might stop working. To check:
-
- Open your browser.
- Open developer tools (usually via F12 or right-click → Inspect).
- Go to the Network tab.
- Locate Your JWT Token
-
- Navigate to your Sisense instance and attempt to log in via SSO.
- In the Network tab, look for the request containing "jwt" in the URL.
- Highlight the request and open the Headers tab.
- Copy the request URL and paste it into a text editor.

- Decode the JWT Token
-
- Extract the JWT token from the request URL.
- The token is the string between "jwt=..." and "&return...".
Example screenshot
-
- Use a JWT debugger such as jwt.io to decode the token.
- Check the decoded header section for the "typ": "JWT" attribute.
Example header:
{
"alg": "HS256",
"typ": "JWT"
}- Fix the Token Generation
-
- If "typ": "JWT" is missing, update your SSO script to explicitly include it when generating the token.
Example:
-
- Regenerate the token and reattempt login.
- Verify the Fix
-
- Repeat steps 1–3 to ensure the "typ": "JWT" attribute now exists in the token header.
- SSO login should now work without errors.
Conclusion
A missing "typ": "JWT" attribute in the JWT token header can cause SSO failures after upgrading Sisense. By inspecting the JWT token and updating your SSO script to include this attribute, you can restore SSO functionality quickly.
