What's the net::ERR_HTTP2_PROTOCOL_ERROR about?

Question

I\'m currently working on a website, which triggers a net::ERR_HTTP2_PROTOCOL_ERROR 200 error on Google Chrome. I\'m not sure exactly what can provoke this erro

Answer 1

For my situation this error was caused by having circular references in json sent from the server when using an ORM for parent/child relationships. So the quick and easy solution was

JsonConvert.SerializeObject(myObject, new JsonSerializerSettings { ReferenceLoopHandling = ReferenceLoopHandling.Ignore })

The better solution is to create DTOs that do not contain the references on both sides (parent/child).
