Environment Details

  • Python 3.7.12
  • google-api-core 1.23.0
  • google-auth 1.35.0
  • bigquery 2.3.1
  • let me know if i can provide any other library versions

We are querying some data from bigquery using python in airflow, and converting results into a dataframe. See this chunk of code:

from google.cloud import bigquery
bq = bigquery.Client()
query_result = bq.query(f"select count(*) as num_rows from our_project.ourdataset.our_table")
our_df = query_result.to_dataframe()

query_result is a <google.cloud.bigquery.job.query.QueryJob object at

When we run the last line our_df = query_result.to_dataframe(), we get the error TypeError: secure_channel() got an unexpected keyword argument 'default_scopes'. The whole error message is:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

This line of code was previously working for us. The only change I recall us making since the code was last working was:

  • Installed dbt==0.19.0

to.data_frame() seems like the most basic python function there is, and it is quite frustrating that it is not working here for us. What can we do to resolve this?

I've found the issue, but I have no idea how to resolve. dbt-bigquery 0.19.0 depends on google-api-core<1.24 and >=1.16.0 When we installed dbt, it must have changed the google-api-core version from something greater, down to 1.23.0. However, google-api-core being as low as 1.23 is now causing this other issue with to_dataframe(). I know this because when I manually upgraded google-api-core to 1.26, .to_dataframe() was working again.

EDIT: upgrading dbt to 0.20.0 allows for google-api-core 1.3+, which resolves our issue!

For me upgrading google-auth, google-auth-httplib2, and google-api-core did the trick.
