[arielshaqed]

What happened?

What actually happened, including error codes if applies.

Steps to Reproduce:

1. Configure (on lakeFS.Cloud) your user not to be allowed to read README.md. Stanza for policy:

   {
     "action": [
       "fs:*"
     ],
     "effect": "deny",
     "resource": "arn:lakefs:fs:::repository/*/README.md"
   }

2. lakectl gives correct error message:

   $ lakectl fs cat lakefs://sample-repo/main/README.md
   insufficient permissions
   401 Unauthorized

3. WebUI gives minified or otherwise weird error message:
