You should look at the server logs or the output from the console. That
should hopefully provide some details on the reason behind the "Internal
Server Error".

Kind regards,

That error message should be fairly obvious. You haven't defined
anything called JsonResponse.

You most likely just need to import the correct module. I don't know
what that would be, but it would probably be from the library you use to
generate JSON responses whatever that might be.

Kind regards,
