Hi @T.Yorimitsu ,

I've seen several report of this error where the agent (pangps.exe) sends response to pangpa.exe after removing webview2 filters. It triggers SAML auth.

This issue happens when SAML auth Popup is closed.

If you're running into this issue then there's no workaround at this time.

Note that GP v 6.3.3 is not a preferred release at this time:

Please reach out to TAC to confirm if you're hitting this exact bug of if you're hitting a different issue.

Kind regards,

-Kim.

Hi, @kiwi

Thank you so much!!

Do these error messages output when the SAML configuration is enabled?

-Currently, SAML is not configured.

Best regards.
