Script Error Popups in ZApp During Login when Using Google SAML

OS: Windows 10

We’re getting IE Script Debug popups during the initial login to ZApp after deploying it to users.

Users have to keep clicking “Yes” on several of these popup messages in order to login to ZApp with their Google credentials. Some resources on the Google login also fail to load making it more difficult to login with 2FA.

Just wondering if anyone else has encountered this issue and what the solution was. We have tried adding to IE’s trusted sites list to no avail. ZScaler Support advised that it’s an IE caching issue but clearing the cache & temp internet files doesn’t seem to help. I have also tried disabling Scipt Debugging in the IE settings.
