alpreu opened a new issue, #18253: URL: https://github.com/apache/pulsar/issues/18253
### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Motivation When sending invalid JSON to the `pulsar-functions-worker` API the response from the server looks like this: ``` {"servlet":"org.glassfish.jersey.servlet.ServletContainer-53f0d09c", "message":"Bad Request", "url":"/admin/v3/sinks/public/default/SinkTest", "status":"400"} ``` The problem here is that there is no descriptive error message that shows the user that the sent JSON is either broken or could not be mapped correctly. To reproduce the issue, start Pulsar in standalone mode and send an invalid `sinkConfig` json to the sink creation endpoint: ``` curl -X "POST" "http://localhost:8080/admin/v3/sinks/public/default/SinkTest"; \ -H "Accept: application/json" \ -H 'Content-Type: multipart/form-data; charset=utf-8; boundary=__X_PAW_BOUNDARY__' \ -F "sinkConfig={\"xyz\"};type=application/json" -vvv ``` ### Solution The solution is to override the default `ExceptionMapper` from Jersey. Unfortunately,this seems to be a rather difficult problem, as we also include `jersey-media-multipart` and `jersey-media-json-jackson`: https://stackoverflow.com/a/30371823 ### Alternatives _No response_ ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
