Ran into the same problem, seems to be 2.27 only, I worked my way to 2.26 without problem.

We got the same issue at multiple customers.
When I test with v2.26.0 it just gives another error,

Update-MgServicePrincipal : Cannot convert the literal 'MIIDQzCCAiugAw…DKkjNd34V6Fb+kGm...' to the expected type 'Edm.Binary'.
Status: 400 (BadRequest)
ErrorCode: Request_BadRequest

Please update to the latest version 2.28.0
