Frequently needing to clear browser cache - Experience Builder: Enterprise 11.5

Andrew-Bowne — Wed, 16 Jul 2025 16:10:36 GMT

Anyone have to constantly clear your browser cache so that ExB apps display in both the builder and during runtime?

Specifically, I am seeing React errors in both Builder and when the app is running. I don't have an example screenshot of Builder error(s) but here is one at runtime. (apologies, it was sent from to me from a user who doesn't know how to use print screen 😂)

This happens in Chrome, FF and Edge and didn't happen until I upgraded to 11.5.

Thoughts?

Hey @Andrew-Bowne

I recently upgraded from 11.2 to 11.3, and our Chrome and Edge users had quite a few problems with cached files, give this a shot here:

First, try in Chrome, press Control + Shift + Delete and follow the arrows:

Make sure it's set to Everything and the file cache, give it a reset and let me know if this ends up working, if not, could you provide a screenshot of the console and network panel on the developer window (f12).

Yup, did that. I also went into dev tools-->application and cleared out all storage. It still happens randomly. Next time it happens (because it will happen), I will grab a screenshot and post it.

I would like to say it's isolated but I have had several reports of this behavior. Clearing the cache works, but it seems to only be temporary.

I'm also seeing this issue as well! I have had users needing to clear cache multiple times and I have had React-130 errors numerous times and even having Layer Panels not appearing, just blank.

This seems like a server-side issue, we are still confirming the root cause.

.."Layer Panels not appearing, just blank..."

You mean like this???? This just happened for me in the map viewer:

Dev Tools:

Then after clearing cache and hard reload, the layers "reappear":

A patch has been released that might fix this issue:

I've been having this issue specifically with services shared publicly. Specifically, I keep getting the prompt to enter credentials for our Enterprise Portal to access resources that have been shared with the public. It's not a huge deal for me to clear my browser cache to make the problem go away, but the average resident-map-user would not think to do this, and shouldn't have to. I just applied the Applications patch, so we'll see if the issue crops again - did anyone else experience something similar that was solved by applying the patch or through some other fix?

Hi @ZachBodenner -At times, opening an ExB app in Edit mode in the Online ExB Editor I will receive the prompt that I need to enter my credentials for our Enterprise Portal. I enter them and then I'm fine.

All of the layers we use are collaborated over from Enterprise by reference but all are shared 'with everyone' on both sides. Nevertheless, I'll still receive the prompt from time to time.

After the Online update, we started to receive non stop source error reads in our Server logs for 'null' reads:

https://community.esri.com/t5/arcgis-enterprise-questions/request-error-percent-alerts-by-the-thousands/td-p/1660624

Recently, in the last week or so we now get this little prompt from Chrome while opening an Experience on our Network:

Fortunatly I'm not seeing this prompt off-network, i.e when I open one of my ExB's on my phone....

I've got a case with support but who knows. We've been grasping at straws.

Hm, that's interesting, it sounds a little different than what I'm getting because I don't get prompted in the builder, only once the code is deployed on our server. I too have a case open so I'll stop back here if everything comes of it.

Yeah I mean we're only working in the Online builder so we're obviously not compiling from the dev edition and hosting on our web server. If I hear anything I'll post back as well. But I'm seeing all kinds of problems all over the community spaces since the October update and the Living Atlas 2025.2 content update for Enterprise. Last time I saw anything like this was with 11.3 Enterprise not updating properly - that turned out to be a culture / local issue - e.g. 'en-US'

So it turns out that the access prompt is a new feature in Chrome:

https://developer.chrome.com/blog/local-network-access

Because our Online webmaps that populate our instant apps and experiences are consuming layers from our Hosted Enterprise Site by-reference collaboration, the calls to the layers in said webmaps are causing Chrome to throw up the Access Prompt that I show in my earlier screen grab.

If the on-network user clicks 'no', the apps still work but throw CORS errors in the console. If the on-network user clicks 'Allow', no errors....

Who knew? Not great but what can you do?

Yeah I wish my issue was that simple!
