Error: getCredentials(): Return value must be of type array, null returned

Created a patch to check that $credentials is an array before returning it.

Nice catch! I think it's more readable to do it like this:

 return $credentials ?? [];

Since the key module call is enforcing arrays and the state call is either our array or null.

Updated with null coalesce

Super! It also occurs to me that we should add a kernel test for this case that verifies the fix.
