Hello @rogerlzp, thank you for reaching out. I apologies for the delayed response. We will need some additional information from you in order to review your report. Can you please provide the following information:

• What is the path to the code sample that you have a problem with?
• Did you modify any file of the code sample in your steps to reproduce the problem?
• Given the reported exception is com.google.iam.v1.TestIamPermissionsRequest what are permissions of the identity you used to run the code sample?

I am temporary assigning this issue to you to reflect the status. Please, assign it to @minherz or @Sita04 once you provide this information.

Thank you
