I see that my google-auth version is old (1.6.3), so maybe this is actually an issue of my not upgrading all dependencies properly.

[arithmetic1728]

@nitramsivart yes, please upgrade google-auth. mtls is not defined in the old version.

[nitramsivart]

Thank you, that resolved my issue!

[nitramsivart]

Note, this is still an issue when I install this package with conda install, because these dependency requirements haven't been updated in the conda recipe: https://github.com/conda-forge/google-api-python-client-feedstock/issues/39

[busunkim96]

Hmm, I'm not entirely sure how this package is published to conda. @meredithslota?

[nitramsivart]

Pretty sure it's published using conda-smithy, as described a bit more in README of this reop: https://github.com/conda-forge/google-api-python-client-feedstock

What's unclear to me is if anybody owns keeping this up to date, or it's just as needed

[busunkim96]

Closing as this has been addressed by the folks who manage the repo mentioned above.

I still get the error even though my pip list shows the version google-auth 1.17.2

I am using that in a Jupyter Notebook with Python 3.

[busunkim96]

@A-Sm1th Can you double check the version? The latest published version is 1.9.2

[arithmetic1728]

@A-Sm1th I tested google-auth 1.17.2 and it worked fine.
