-------------------------------------

Thanks Chesnay - I didn't even see the request/response buttons! I'll close out this issue.

>                 URL: https://issues.apache.org/jira/browse/FLINK-14864
>             Project: Flink
>          Issue Type: Bug
>          Components: Runtime / REST
>    Affects Versions: 1.8.1
>         Environment: Running 1.8.1 on an AWS EMR cluster. Making a POST request with NodeJS (request library).
>            Reporter: Kelly Smith
>            Priority: Trivial
>
> The documentation specifies that you should provide a parameter called `programArg`.
> *Repro*
> Send JSON as a POST body to */jars/:jarid/run* with `programArg` as a parameter
> *Expected*
> Successfully starts the job passing in the values from `programArg`
> *Actual*
> **Returns error:
> ```
> {"errors":["Request did not match expected format JarRunRequestBody."]}
> ```
>  
> Digging into the source code, it appears that _JarRunRequestBody_ expects the field to be plural: `programArgs`
> [https://github.com/apache/flink/blob/master/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/handlers/JarRequestBody.java#L44]
>  
> Changing the name of the parameter to `programArgs` results in the job being successfully submitted with no error.
