> There is a crash in the nifi web api on posting empty payload via curl to versions/active-requests endpoint. It seems the request is not validated to be null and causes NullPointerException.
> There should be a null check to throw exception stating request should not be empty before getting group ID at [https://github.com/apache/nifi/blob/4d940bb151eb8d250b0319318b96d23c4a9819ae/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-web-api/src/main/java/org/apache/nifi/web/api/VersionsResource.java#L263] .
> I would like to contribute a patch to nifi with the fix that I have already tested manually. I am a new contributor so any help on this will be appreciated.
