Script error when trying to log in through 4.2 plugin

[DougW]

all our users started getting the two script errors below when trying to sign in using the the 420 plugin. regardless of whether you select yes or no, result is the same, blank login screen. we can login fine through a web browser but not through Civil 3D 2023. any one else running into this or know of a solution?

Hey @DougW and @AllenP,

Are either of you using SAML with ArcGIS Online? Or just built-in user accounts.

[DougW]

We're just using built in user accounts.

Hi Dan, our organization started having this issue as well this week. I've upgraded to ArcGIS for AutoCAD to 430.1 and still recieve the same error. We are using SAML but the error occurs before you identify if you're using SAML vs built-in user accounts.

[DougW]

I believe ArcGIS Online... but not sure how I would know for sure. And yeah, the 430.1 plugin had the same script error & it did load in 2025 but again, same error.

The guy who setup ArcGIS online here is no longer here. I'm the AutoCAD guy & administer the ArcGIS online users.

Hey @DougW, @AllenP and @CallieW,

This behavior should be fixed perhaps Friday, August 23, or Saturday morning. Check the blog from @MichaelDavidsonPM  post above for any further developments.

Thanks for your patience!

Hi @DougW , @AllenP , and @CallieW, 

Your teams should now be able to sign into their ArcGIS Online organizations using ArcGIS for AutoCAD.

Thanks again for letting us know about this issue and for your patience over the past two days.
