@ashuvashu You have an out-of-date version of google-cloud-core installed in your environment. google-cloud-bigquery 1.12.0 and later require google-cloud-core >= 1.0.0.

I'm getting this error as well, and I have updated all google cloud python libraries. I have google-cloud-core v 1.11.1.

@ctivanovich Can you please show the requirements.txt for your Cloud Functions environment?

I have found that this requirements.txt works on a fresh Ubuntu 18.04 install:

google-cloud-bigquery==1.19.0
google-cloud-core==1.0.3

By "works" I mean you can create a BigQuery Client object and obtain a Table object from it.
