How to resolve error 415 Unsupported Media Type when Content-Type is correctly set

Question

I have a simple POST request that requires a json Content-Type header and a body like

{
   oneNbr: \"2016004444\",
   twoCode: \"@@@\",
   threeNbr: \"STD PA         


        

Answer 1

We did some debugging and found that Karate automatically appends 'charset=UTF-8' to the Content-Type header. The API does not expect charset.

Found the following post and that solved the problem:

How can I send just 'application/json' as the content-type header with Karate?
