Environment
All supported DevTest releases.
Cause
The Portal was caching a file location that no longer existed under LISA_HOME\Projects
The Portal was looking for LISA_HOME\Projects\res-hub\v1\projects
That no longer existed.
Resolution
1) When we logged into the portal as admin, would get an error 500 Problem accessing /res-hub/v1/projects. Reason:
2) This problem started when added a new license back on 10-19-2020
3) Stopped the Portal and other services.
4) Delete the lisatmp folder to clear logs and all cache information.
5) Moved the 2 additional renamed license files to a backup directory in the LISA_HOME folder
6) Started the Portal and other services and noticed there is still an error.
7) When on the physical server for the Portal looked at the LISA_HOME\Projects folder> Did not see a folder called /res-hub
8) Went back to the Portal and did a refresh on the projects list and then logged out and back in.
9) No longer were getting the error.
10) Tested this with both IE and EDGE and saw no further errors.
It looks like the Portal had cached the project path for a folder that was no longer valid on the file system.
Once we refreshed the list and changed it to an existing project, no longer saw the error.
