Hello. I’m facing an error with Apache HttpClient. I’m sending request inside runBlocking code block and sometimes it throws an error:

java.lang.IllegalStateException: Unexpected request state READY

The request Type is POST, with body being an Map object, which is being parsed to json using jacksonObjectMapper. Does anyone have a clue, what could lead to such an error, which is not 100% reproducable?
