[danni]

Tell me more about your setup. Is this building the released version or master?

[wjmelements]

From our Pipfile

python-pkcs11 = { git = 'https://github.com/danni/python-pkcs11.git', ref = '1bab4197f1098b6933dda2a12c5100f6d92cd706' }

[danni]

And what platform/architecture?

[wjmelements]

Docker image: python:3.7.3-stretch

https://github.com/docker-library/python/blob/34c9df35e9a69e9f0edde88e861b543edb8bc07a/3.7/stretch/Dockerfile

[wjmelements]

The pkcs11 library is CloudHSM

[danni]

I think I've messed up a signed/vs unsigned integer somewhere here. Does it work without the filter?

[wjmelements]

I have not seen the issue without the filter.

[cormallen]

I also get this, and I get with or without a filter.
