Describe the bug

Getting an JSON syntax error after entering azure cloud credentail

SyntaxError: Unexpected token S in JSON at position 204

Seems to happen randomly. Sometimes happens, sometime not.

Seems to occur more often when there are no cloud credentials stored.

To Reproduce

. Add AKS Cluster . Add Cloud credential

Result . UI displaying error message after entering an azure cloud credential.

SyntaxError: Unexpected token S in JSON at position 204

Expected Result

No errors after entering cloud credential

Screenshots

Additional context

Cloud credential seems to work afterwards, so perhaps just an erroneous message.
