Experience Builder in ArcGIS Enterprise 11.5 Constant React JS Error

DavidColey — Thu, 24 Jul 2025 20:24:27 GMT

Hello -

I am constantly getting the following error message in the ArcGIS Enterprise 11.5 Experience Builder IDE:

Minified React error #130; visit https://reactjs.org/docs/error-decoder.html?invariant=130&args[]=object&args[]= for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

Each time I get the error, one component or another will not load. Sometimes its the Draw Widget, other times its a List, still other times its the Map Layer widget.

Point is, when it happens I can't update my apps. I have asked my security team if we have something in place blocking content from reactjs.org, but so far I have not heard back.

Thanks,

David

Hey @DavidColey

Would it be possible to clear all your cached files? Is this a recent upgrade as well? If so it could be some files retaining in your browser cache which may be breaking it. I would attempt this on another browser or possible an incognito window first!

I'm seeing the same thing. Sometimes it's the table widget, sometimes it's in the ExB editor "Theme" pane. It renders both the app editor and apps themselves unusable. I reached out to support and they believed that it was tied to a known bug that they are working on as a high priority: BUG-000177808 The onscreen react error messages don't seem to align with the bug documentation, but support spoke confidently that it was connected.

Worryingly, it's listed as "Fixed" in reference to Enterprise 12.0... This doesn't help us if 11.5 remains broken, so we can't work toward replacing our WAB apps. And even when 12.0 is released, we can't move there without first having replacements for our WAB apps. Apps that remain irreplicable using ExB's current capabilities.

I see this in both Edge and Firefox. Firefox Private windows may allow you to continue working, but the apps still aren't loading perfectly.

Thanks for the reply @CodyPatterson - Like I said, this is Enterprise 11.5 Experience Builder, so whatever the version matrix says the Enterprise 11.5 build is, then that's what I'm working with. I always work in Chrome Incognito, and always work with a cleared cache (multiple times per day - a habit from my earlier js developer days) but have since modified that approach as Incognito blocks third party cookies - and ESRI/AGOL etc uses many third party cookies.

I move over to Edge sometimes when I see the error, but that seldom helps as @JDenham noted in his reply, Firefox isn't an option for us - nor should it be required for anyone.. grr.

One of my biggest headaches that remains is ESRI production reliance on github. GitHub access is mostly blocked as a security threat by our EIT Security Team.

Well, so far this morning things are working..... no component load errors from reactjs.org so who knows . . .

Hopefully ESRI can release a patch for version 11.5 shortly to fix BUG-000177808

To anyone thinking of upgrading to version 11.5... DON'T DO IT until this issue is fixed. It's a major issue that makes most web apps unusable.

Well, for those of us that are already at 11.5 like myself, I would not not say 'DON"T DO IT' in terms of upgrading to 11.5. I would say, 'If you have critical Experience Builder apps that you are configuring through Portals' Experience Builder Editor, you may want to hold off unless you MUST have updated widget functionality, like the Text tool that is now part the Draw widget (or other 11.5 enhancements)

I haven't experienced any real issues with my Instant Apps accessing CDNs or other loaders.

And although I am experiencing these loading issues for the ExB, usually if I wait and/or reload a few times I am then getting everything to load, and so can make small changes and then re-publish.

I would say 'DON"T DO IT' in terms of publishing an ExB when the CONTENT has not loaded.

Lastly, what does seem to be frustrating is the Bug fix report does say 'fixed' but I don't see a Portal patch out yet and the Patch Finder on the portal machine is not finding one either.

EDIT - Now I see that the report says this bug is fixed for 12.0 release which is great but that definitely doesn't help us out now . . .

Just noticed this problem today, after upgrading to 11.5. Happened when I entered the experience builder (edit an existing WebExp file, or create a new WebExp), and on Ms Edge. Launching the already-published apps are good though, as long as not entering the Experience Builder page with MS Edge.

Tried using Chrome (Standard version, non-incognito), both before and after clearing cache it worked fine.

This is my screenshot when using Ms Edge.

My current workaround is to work using Chrome.

Yup that's what keeps happening to us too @JuanMarvinW . . . I'm hoping they put out a patch for 11.5

I experienced these issues today. I got the minified react error and my ExB app stopped working. All apps wouldn't open and I can't even open ExB from the apps console. This is a clean install of 11.5 for us and we were going to rebuild everything from WAB to ExB.

Looks like a patch has been released:

Re: Experience Builder in ArcGIS Enterprise 11.5 Constant React JS Error

DavidColey — Thu, 07 Aug 2025 19:49:48 GMT

yes this definitely looks like this should resolve both the "Chunk" error and the (hopefully) the React.org resource access errors. Thanks for the post reply on this @mwartman_grey , I don't know why I don't get these patch notifications any more. I'll apply tonight and we shall see.

Yes both the ExB editor and the Instant app config page show no errors when modifying my apps, behavior feels more solid. Thank you esri.

Version 12.0 fixed these issues?
