Is it possible to validate JSON object schema without converting it to string? I just want to validate it, not convert.

Yes, the node has the option to ensure the output is a particular type ... I can't remember the exact words we used in the option, but it's there.

Actually, having had a quick look at the code, it appears it only validates when doing the conversion. If the payload is already the required type, it doesn't validate.

[image] dubnemo: therefore this capability should in the JSON node. Yes we agree. We added support for passing in the schema in with the message as a pragmatic enhancement that didn't require any changes to the UI. I would be great to get the UI updated - just needs someone to offer up their…

Of my 39+ years of integration and 10+ years of working on open source, I can confidentiy state that nothing gets fixed unless someone steps up to help. We look forward to your contribution.
