With no changes we have started to get the above error. 

We get it with the 1.7-py3 stack and the 1.8-py3 stack

We have tried upgrading our requirements to the latest but still the same error.

The error seems out of our control.

Could it be this pip issue? https://github.com/pypa/pip/issues/7217

We have tried to specify a pip version in requirements.txt but we just get a different error (and it's not recommended)

Thanks
