"There is a JavaScript error in your browser console" keep showing in Employee Center Portal every time I open and reload the portal after we upgraded the instance from Vancouver to Washington.

This is the Source:

This is the Error message:

@asinmar Please check if any widgets have been customised on your instance and check if any of those customisation broke during the upgrade to Washington. If the debugging doesn't work, try to raise a case with ServiceNow support and get their help on this issue.

[asinmar]

Thank you for your response. We contacted the HI support; the error is in the Washington version itself. They will apply fixes in the upcoming patch.

Do you know what Patch version is supposed to fix this issue?

I am seeing the same err in UI Builder when loading a page - the main/center content screen is blank when this err is in the logs.

currently having this issue with employee center even with the patch installed.
