I start policy-clamp with OOM Istanbul release. I start clamp UI and click "Upload Tosca to commissioning", but the process always failed with 500.

I have checked the clamp-be logs, it indicated authentication failed during the process, since it is not able to get the user principal name, thus it uses "Not Found". Detailed lots shown below:

I have logged in successfully and I see the user name present correctly in the UI.

When clicking User Info, the result is also correct

I also tried other activities, e.g. "View All Loop Templates", and the authentication was also fine.
