[BUG] bool type error

See original GitHub issue

I believe I have found a bug in drf-access-policy. During some requests I receive the following 500 error:

The error seems to stem from File "/usr/local/lib/python3.8/site-packages/rest_access_policy/access_policy.py", line 181, in _get_statements_matching_context_conditions

Thanks 🙂. I’ll plan to do the 1.0 update later today, it’s pretty minor, the main thing is communicating the breaking change in the docs.

@rsinger86 https://github.com/rsinger86 Thank you for your response and for this project! It has really helped ease the development of my product.

How can I go about avoiding this issue (Im planning on opening up my project to beta and this is kinda the last blocker)? I’ve seen this happen with both simple method conditions as well as a basic complex expression e.g. (is_adminoffice or is_sysadmin) so I’m not really sure how to stop/avoid it. I can also downgrade to 0.8.6 if this error does not occur there.

Thank you again for your help.
