JSON serializer can't serialize binary data: UnicodeDecodeError: 'utf8' error about vcrpy HOT 7 CLOSED

Any updates on this issue - I'm having the same issue and would prefer to use json over yaml for the serializer due to performance issues loading in the yaml file.

from vcrpy.

Maybe a new serializer: base64-encoded json???

For the yaml performance issue - make sure you are using the libyaml c bindings instead of falling back to the pure python implementation - it’s a lot faster.

yeah looks like it's having trouble serializing the binary data.

Any plan on a fix for this issue

Sorry, I've been really busy and haven't had a chance to check it out. Do you have the same problem with the yaml serializer?

It looks like the problem is that JSON can't serialize binary data. The response contains the binary zip file, which can't be encoded into UTF-8.

I'm not sure what the solution here is. I could base64 encode the response string, but that would break backwards compatibility with old JSON cassettes as well as defeat the ability to open the cassette file to inspect the response for debugging purposes.

Sorry forgot to mention, it does work with yaml
