๐Ÿšซ API cause a null response after click on ListView

PI call that retrieves messages from Beds24 (a channel manager that connects Airbnb and Booking.com).

As soon as I click on one of my travelers' messages, all my API calls in my App return a "null" response.

I don't understand why.

My other API calls work very well and without causing any cracks in the application. All my calls are "Private".

Do you have any ideas for solving this problem?

Best regards
