Incompatible with latest version of google-cloud-bigquery

[edu230991]

pandas_gbq currently has unconstrained dependencies.
Yesterday a pretty key dependency like google-cloud-bigquery released a new version (https://pypi.org/project/google-cloud-bigquery/#history) which is incompatible with pandas_gbq at the moment.
I would strongly recommend constraining dependencies to avoid this in the future!

Thanks for letting us know, looking into this.

Could you give me an example of how exactly they are incompatible? It would be really helpful, thanks. @edu230991

I wonder if it's related to this test failure? #855

dtypes = {}
        for field in schema_fields:
            name = str(field["name"])
            # Array BigQuery type is represented as an object column containing
            # list objects.
>           if field["mode"].upper() == "REPEATED":
E           KeyError: 'mode'

pandas_gbq/gbq.py:609: KeyError

It seems it may have been caused by my refactor of SchemaField. googleapis/python-bigquery#2097 where the "mode" no longer is populated to "NULLABLE" if not set.

Indeed, this seems to be the cause.

That's exactly it, sorry for not being more specific

I will yank 3.28.0
