Hi, I have a working NiFi installation on both my local machine and on a cluster. Both set up with certificates and https access and LDAP integration. All good. However, I have come across an issue where I can’t now export templates as I get an ‘access denied’ error in the UI, and in the nifi-user.log I get this stack trace…

The resultant url for the export is https://localhost:9090/nifi-api/controller/templates/92427c50-2d9b-4a9b-83eb-4062c9c88d49 if that helps. I also have two tokens set in local storage of ‘jwt’ and 'nifi-view-a96be08b-00c9-4ebb-ae11-84101cca90ad’.
