GCloud powershell commands throw error but works fine in cmd - powershell

Question

When I run GCloud comannds via windows cmd prompt it works.
But when I run them via powershell it throws an error in red, but the command gets completed successfully.
Eg:
1) Auth
gcloud auth activate-service-account xxx#xxx-xxx.iam.gserviceaccount.com --key-file=C:\xxxxx\cred.json
Error:
python.exe : Activated service account credentials for: [xxxx#xxxx.iam.gserviceaccount.com]

+ & "$cloudsdk_python" $run_args_array
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (Activated servi...iceaccount.com]:String) [], RemoteException
+ FullyQualifiedErrorId : NativeCommandError
2) Upload file to storage bucket
gsutil cp $outputFile gs://bucketxxx
Error:

Answer 1

I was not able comment, hence adding my inputs here.
First : The issue only seems to occur when this is run via Powershell ISE and not when executed via powershell prompt.
Second : This is not as such an error, for example when you see your own error you find the text after Not Specified as "Activated servi..." which means the action is sucessfully performed. Hope this helps to someone else stumbeling over here
