Test IAM Permissions generated code failing

[kolea2]

In a recent regen for Bigtable, it added:

https://github.com/googleapis/python-bigtable/pull/216/files#diff-9bbb5ea4e132c72b65ab1881c88e2ab4580a237b5bd8e4f4e8709a68a564f79cR2050-R2052

The generated test is now failing with the error,

E           AssertionError: assert ['permissions...ssions_value'] == ['permissions_value']
E             Left contains one more item: 'permissions_value'
E             Full diff:
E             - ['permissions_value']
E             + ['permissions_value', 'permissions_value']

I believe it is re-appending the permissions value incorrectly (the permissions are already set here). Please let me know if you need any more info. Thanks for the help!

Checking in. Any progress on this by chance?

I also observed this on google/cloud/tasks, so I suspect it is widespread (probably any API with test_iam_permissions?). This replace was enough to get the unit tests passing again:

s.replace(
    "google/cloud/**/client.py",
    """\s+if permissions:
\s+request\.permissions\.extend\(permissions\)""",
    "",
)
