Adding sendgrid==6.3.1 (in the requirements.txt) is the workaround that we plan to use for now.

Opened a PR to add the required dependency to the package requirements. Thanks for catching this!

Faced the same error in Ubuntu 18.04 while using in my flask app after updating to 6.4.0
It was working perfectly in the previous version

Updated using the command

pip install sendgrid --upgrade

A PATCH version should be released to fix the issue

Facing the same problem

Facing the same problem too. What's the official workaround until the patch is released?

[iamareebjamal]

To not upgrade

[meteatamel]

To problem was, my Dockerfile was installing the latest Sendgrid by default. As someone suggested, I added a requirements.txt file and set the version to 6.3.1 to work around it for now.
