posting invalid JSON causes HTTP 500 rather than HTTP 400 #87
Comments

Also the comment in suggests an HTTP 400 should be returned |

Thanks for the report. This is actually a problem in the underlying rest-utils module as you've discovered and is already being tracked in confluentinc/rest-utils#9. |

Hi Team, I am getting the same JSONParseException for kafka-rest proxy. Posting valid JSON data with AVRO content-type, |
|
@yogeshsangvikar It looks like the content you are posting to the REST proxy is not valid JSON. As mentioned above this is being tracked as a bug in rest-utils insofar as we would like to provide a better error message. But you can also track the problem down at the client by logging the payload you are sending and validating that it is correct JSON. |
posting an invalid JSON snippet causes an Http Internal Server Error 500 response, rather than an Http Bad Request 400 one because of unhandled exception
example request (note that after key there should be a : not an =)
POST host:8082/topics/edotopic
Content-Type: application/vnd.kafka.binary.v1+json
{"records":[{"key"="aw==", "value":"S2Fma2E="}]}
log:
