When I try to create a VM with labels, the package converts the keys from kabab-case to camelCase, and I get an error:

Invalid value for field 'resource.labels': ''. Label key 'iAmVm' violates format constraints. The key must start with a lowercase character, can only contain lowercase letters, numeric characters, underscores and dashes. The key can be at most 63 characters long. International characters are allowed.

The labels I try to add:

labels: {
        'i-am-vm': 'true',
      }

The bug occurs only in version 3.1.3. When I downgrade the version of the package to 3.1.2, It works

1. Is this a client library issue or a product issue? Library issue
2. Did someone already solve this? No
