JSON Responses becomes stringified whenever it passes proxywoman

[asomethings]

Json responses from orig servers becomes stringified json whenever it comes through proxywoman. The part that i can't understand that is https://postwoman.apollosoftware.xyz/ proxy works fine and it gets data by json.

Is there any chance that i could be missing something?

I've tested with both same link which is https://projects.propublica.org/nonprofits/api/v2/search.json?order=revenue&sort_order=desc

How to reproduce (Tested with Linux / Windows / Docker(Linux))

1. Start Linux/Windows Proxywoman server.
2. Request https://projects.propublica.org/nonprofits/api/v2/search.json?order=revenue&sort_order=desc
3. Check response from proxy server

Sample response (Truncated organizations) from my local proxywoman
