Frequently Asked Questions
Why do script errors occur during Power BI sign-in?
Script errors typically occur when the embedded browser component used for the sign-in prompt fails to correctly process the JavaScript from the authentication provider, such as the GoDaddy portal.
Does clicking 'Yes' or 'No' on the script error fix the issue?
No, clicking either 'Yes' or 'No' usually dismisses the prompt only temporarily. The error will likely reappear because the underlying script conflict during the authentication process remains unresolved.
How can I bypass the GoDaddy portal script error in Power BI?
Workarounds often include clearing the cache of your default browser, ensuring the WebView2 runtime is updated on your virtual desktop, or consulting the Power BI Community for specific configuration adjustments related to the PL-300 lab environment.
