[Python] Django POST error: response variable not associated with a value error

This one for python wizards. I got next code in some of my messenger class:

response: Dict[str, Any] | None = None
try:
response = self.client.post("url/", data=payload)

if not response or not response.get("ok"):
logger.warning(
"[MessageService sync_chat] " +
"Server responded without confirmation (ok=False) for chat '%s'",
chat.chat_id
)
return {"status": SyncStatus.NOT_CONFIRMED}

self._mark_messages_as_synced(messages)
logger.info(
"[MessageService sync_chat] " +
"Synced %d messages for chat '%s'",
len(incoming_messages), chat.chat_id
)
return {'response': response, 'status': SyncStatus.SUCCESS}
except Exception as e:
logger.warning(
"[MessageService sync_chat] " + "Skipping chat '%s' due to error: %s\nResponse: %s",
chat.chat_id, str(e)
)
return {"status": SyncStatus.ERROR, "reason": str(e)}


And somehow I got an error in this try-except block:

WARNING [MessageService sync_chat] Skipping chat '7925606@c.us' due to error:
cannot access local variable 'response' where it is not associated with a value


Even if I initialized response before, python still got no access to it. Because of that, I can't even check what is wrong with my request.
