It turns out our hosting provider has become more stringent with handling http/2 requests and no longer likes GET requests with a request body. Skara currently always fills in the body of a request, regardless of type, with an empty JSON document '{}' when the body is empty. This seems to be faulty behavior and we should let empty GET calls be empty instead.
