list_instances is not returning expected Instance type

[gzamb]

I'm migrating from 1.9 to 3.1 and I noticed that the list_instances() method used to return type Instance<google.cloud.spanner_v1.instance.Instance> but with the latest it actually returns the spanner admin instance<google.cloud.spanner_admin_instance_v1.types.spanner_instance_admin.Instance> which does not have the instance_id. Thus I now get an AttributeError.

I'm unsure if this is a bug or if the documentation just hasn't been updated.

Thank you for filing this issue! As part of the migration from 1.x to 2.x, list_instances(), list_databases(), and list_backups() now all return the protos rather than the wrapper classes. So this is not a bug, but rather the documentation being out of date. I will make sure this is fixed for the next release 👍

Ok, good to know. Thanks for the response.
