Resolution

This has been observed when an endpoint improperly sends the deflate encoding to the API Gateway when the API Gateway is not advertising support for deflate via an Accept-Encoding: deflate header. This can be resolved by making the API Gateway accept deflate encoding from that endpoint, which is done by setting an Input Encoding of deflate for the connection. Refer to the documentation on compressed content encodings for further details.
