I'm curious if getting a nil pointer exception when trying to get string version of APIError (using .Error()) documented. The issue arises when we attempt to run operations on the wrapped error field APIError.err. We are able to safely created using the ParseError. However, when we call .Error() method on this error, we call APIError.err.Error() without checking if err field was set.

Environment details

• Package version: gax-go/v2 v2.12.3

Steps to reproduce

1. Create API Error using ParseError
2. Call (APIError).Error() on error.

Making sure to follow these steps will guarantee the quickest resolution possible.

Thanks!
