I have seen that when the REST service encounters an error, it still responds with an html page within which, among other things, the error message is also found. What I was asking is if it is possible to intervene on the formatting of this answer. If it is possible to modify the graphics of this page or eliminate it completely and reply with a simple text containing only the part relating to the error. Thank you

No that's not the way it works if you're using a wwProcess class unless the error occurs in the actual IIS layer (ie. a hard 404 for a static resource). Anything that is routed through to the REST service and that actually hits the REST service pipeline will produce a JSON error message. IOW any request to the script map will produce a JSON response if you're using a wwRestProcess
subclass.

Can i customize this HTML ?
Make sure you are not running in Debug mode.
What you should see is something like this:
Ok, i see what you marked. Can i customize what is returned? Can i add something with "iscallbackerror" and "message" so i can make this response more similar to my Rest's responses?

Yes you can override wwRestProcess::ErrorResponse()
in your process class and return any JSON you see fit. Look at the base method and then copy into your class and customize. All default error responses go through that method.
