I am afraid that the provided information was not enough for us to determine that is causing the issue. Could you provide more details on the specific scenario?
- Which version of the controls is used in your application?
- Under which browser and its version does the error occur?
- Which are the exact pop-up which opening is causing the error? What are the steps to reproduce the issue?
- Could you try the approach from this blog post and see which is the exact resource which is missing?
Could you isolate the issue into a sample fully runnable project and send it for a further investigation?
Looking forward to hearing from you,
