That error is coming from a third-party runtime, so I can’t say anything definitive about it. However, it doesn’t look like it’s related to App Transport Security. Rather, it looks like the runtime is having problems parsing the response it got from your server.

My advice is that you create a small test project that attempts to fetch the same URL using URLSession. If that fails in a similar way, I’d be happy to help you investigate. OTOH, if that works then this is something you should escalate via the support channel for the third-party runtime you’re using.
