Hello John,

I think it will be best if you can open a formal support ticket and send us a simple running project demonstrating the problems. In that way we can reproduce the javascript error on our side, understand the logic of your application and provide a solution.

Best wishes,

Hi Ali,

The issue that you described seem to be web resources related. I suppose that there are some differences in the web.config files of the different environments that cause it. However, as I said in the previous post in order to be able to help you with this problem we should be able to replicate it on our side first. That is why I suggest you open a support ticket and send a sample project which we can debug locally.

Regards,
