ExB 1.9 Dev is broken? Strange errors out of no where when downloading an app package

[ScottHiggins_PVGIS]

Not sure if anyone else is experiencing issues out of nowhere with their 1.9 Dev Experience Builder environments. But two of us are having the same issue in separate environments.

Friday afternoon, I was able to export/download Application packages to put into our hosting environment. I have updated nothing and didnt touch it since the last successful download Friday afternoon 3pm.

Exporting a new edited today, I invariable get "Not found" error or 

And my Server command throws weird errors:

I dont even know why. One our our technicians, separate environment (local 1.9 dev) gets the same error when exporting, or a variation:

So obviously something major is going on with the dev environment. This is putting us seriously behind on our development cycle when we cant even export versions into our test host environment. He exported a version this morning no problem.

Could someone please help, explain what the heck has changed with the stuff, or better yet fix your stuff. This getting to be unreliable as an application development environment. Sigh, ESRI.

Thanks for the post! We are investigating the issue but have not been able to reproduce it. May I know the version of your system and are there any specific steps needed? Thanks!

@TianWen -

I'm not the original poster but am running into the same issue:

• ExP 1.9
• Node v16.17.1
• Lenovo ThinkPad 
• Windows 11

I've tried wiping and reinstalling everything multiple times with no success. The error/s I run into seem to always be related to calcite-components.

Also, everything worked well for many months. This issue seemed to emerge from nowhere.

@TianWen any updates on this?  One of our developers is experiencing the issue on Windows 11, possibly when we bring in arcgis/core package in the custom widget.

Hi,

I had the same error. I have installed Experience Builder in this folder "D:\Programas\ArcGISExperienceBuilder". I created an antivirus folder exception for "D:\Programas\ArcGISExperienceBuilder" and fixed the error. With this antivirus folder exception, now I can download Application packages.

I want to report that by creating the exception in the antivirus did not fix the problem. I'm still researching a solution.

@LuisAntonioRodriguezGonzalez Thank you for the comment. Antivirus software does cause similar problems sometimes. @ScottHiggins_PVGIS @kim_hspartner @chapmunnhsc @RobertScheitlin__GISP Would you try to create the exception in your antivirus and let us know if that works? Thanks!

@TianWen this did not fix the issue for me. Thanks.

[RobertScheitlin__GISP]

@TianWen didn't work for me either.
