Developer Edition 1.12 Cannot Download Site

[LoganCountyMapRoom]

I have started experimenting with Experience Builder Developer Edition 1.12. I followed the directions exactly as the instructions lay out. Upon trying to download the created site, I get an error in the Command Prompt:

I thought there are some deprecation errors with Experience Builder 1.12 and Node.js 18.17.1, so I installed version 16.20.2 (as 16 is the recommended Node version)  and got the same result. Does anyone have a solution or work around to get the site? Is there a version that I can use?

Deprecation warnings are meant to notify developers that something they are doing will be removed from a future version of the software, but that method should continue to work. I get the same warning every time I start Experience Builder. I am running Node 18.16.0 and it is working with Experience Builder 1.12.

Your console indicates that the server is running. Is it working? Your error indicates there is something in that folder when it should be empty. Were you trying to save when it happened? I have an open support ticket with ESRI about occasional save errors in Experience Builder.

The server is running fine. It is only when I try to download the application that I get the error. I have everything saved prior to the export. It will open a site in a new tab that just says "Not Found".

Is there a way to make it delete whatever is in the folder? Not sure if that would be the best solution, but it may be worth a shot?

Maybe one of these posts will help:

The first solution did not work. I do believe the second solution would work, but it requires a successful download to copy the resources folder and config.json file. I do not have a successful download.

I found another post that might be helpful to you. https://community.esri.com/t5/arcgis-experience-builder-questions/upgrading-node-js-in-developer-edi...

Deleting your package-lock.json and running npm ci could be helpful. Deleting the package-lock.json should be safe, but do not delete the package.json or you will not be able to reinstall the node packages.

Also consider just downloading a new copy of Experience Builder and starting over if you have a recent successful build of your experiences you can salvage them using the upgrade guide on the developer site.

I did not have any success with this either. I will try to download everything on a different computer by the end of the week.

I successfully downloaded the zip file on a separate computer. When unzipping the folder (on my local drive, not hosted anywhere currently) and opening the index.html file, I get a "Failed to Fetch" message. Is this normal?  

[JeffreyThompson2]

Yes, the Experience needs to be hosted in order to run properly.

Got it. Looking at the differences between the two computers, only two come to mind:
-The second computer is running on Windows 11 while the other is running Windows 10

-The first computer has an antivirus software while the second doesn't
