Google Chrome: The layer cannot be added to the map.

Question

I have several web maps and apps on ArcGIS Online.  Recently I am getting an error when loading them on Google Chrome.  "The layer X cannot be added to the map".

To test that it was browser related, I was able to run the apps on FireFox and Microsoft Edge successfully with no error.

I've seen some similar posts from 2016 where the fix was to upgrade Google Chrome.  I did that.  Running Version 72.0.3626.96 (Official Build) (64-bit).

After I posted this, I found that clearing the cache is a fix.  If this continues, I'll be back here...

Thanks,

Peter

Hi John,

No. I don't think that I have run into this problem again. But, it has been a while since I've published anything. If I see this again,  I'll be sure to keep you posted.

Regards,

Peter

Just want to revive this question as a few users who I help support are also encountering it…

Peter Hannah did you ever determine what the cause was, and did this issue continue to happen?

For us, it appears to occur when loading a Feature Layer from an ArcGIS Server REST API containing many features (200,000+) in a webmap. When opening the map in Chrome, the layer usually loads fine the first time. Then on subsequent loads, the error you described in your original message occurs. Clearing the cache in Chrome appears to work every time to then get the map to properly load the layer, but the error then soon re-occurs again after a few subsequent map loads.

Also, I am wondering if it is related to the computer hardware people are using. Personally I never experienced the problem using 64-bit Firefox on 64-bit macOS, with 8GB of memory and a Core i7 processor. However another user I know is running 32-bit Windows 7, uncertain how much memory – but it is not as high-end of a machine, and the problem frequently occurs in Chrome (unsure about Firefox).

Curious if others have any thoughts, too…
