Do let me know if any extra info is needed.

Hi @kotesh-arya,

JSON Forms will not add any additional properties by default. There must be custom renderers or JSON Schema preprocessing in place on your side.

Sure, Will check it :+1:
thanks :love_you_gesture:

Re-visited all the places of preprocessing, but still could not find any lead.
Any other places to look out for ?

Is there any json form builder playground that I can use to pass my schema and check ?

You can use the schema with one of our seed repositories or add it as an example in the JSON Forms repository itself and run one of the test applications.

I just tried with the Vue Vuetify renderer set and this is how the “External Product ID” is rendered:
