2. Finish the installation.
3. Run GET call for the REST below whether using browser or any other tool:

   <Base URL>/rest/api/2/permissionscheme

Expected Result:

Actual Result:

• It will returned 500 Internal Server Error instead with error on the logs:

Notes:

• It is caused by the new Application Role on the Project Role.

Workaround:

• Removing of this role on every permissions on each permission scheme will make the REST call possible.
