Wrong encoding in Rasa POST response


I made a bot, which action_default_fallback sends a POST request with the message that it couldn’t understand to another bot, using Python requests. The second bot answers correctly and sends a response, which looks perfectly good, but when the first bot receives the message, all the Unicode characters as ąśżę are encoded (for example, former “wieś” is now “wie\u015b”. I’ve already tried to convert the text to a string, encode, decode, but none of that work. Do you have any ideas? I would be really grateful.

It’s not just one bot, but every bot responds with a message with wrong encoding, and I cannot do anything to decode it.
