Mapview Attribute Store errors going to browser console [infinite loop]

davetinkle — Fri, 10 Apr 2020 21:02:20 GMT

Using 4.14 API, I find immediately after calling buffer, I see about 20 errors per second reading "[esri.views.layers.2d.features.support.AttributeStore] [mapview-attribute-store]: Encountered an error during client initialization"

what's even more alarming: when I navigate away from the offending page & onto one that has absolutely no references whatsoever to the 4.14 API, the errors keep racking up! it's as if there's an open connection that won't resolve, and instead pumps to my console what is effectively a DDOS attack. The only way to get it to cease is to close my browser.

Logging off will NOT stop the flood!

What could be the root cause of this?

I am experiencing

[esri.views.2d.engine.webgl.mesh.templates.WGLTemplateStore] [mapview-template-store]: Unable to fetch requested texture resources

with IE11 since 4.15

The WebMap does not load the Feature Service items to the view.

Test page: here (Esri NL data, hosted on ArcGIS Online) or here (my data, hosted on my Portal)

Esri now lists this behavior as a bug:

BUG-000130303: PNG symbols for PictureMarkerSymbol do not display in Internet Explorer 11.

I have tried multiple times for multiple days to visit your link to the bug, but it will not resolve. Has this been rescinded or promoted? Can you confirm similar behavior when you click the link? Thanks.

Here's an example using a sandbox: JSFiddle

ok, but that has nothing to do with the bug you posted.

please respond to my specific question, so i can understand what you're trying to state.

thanks.

I have this exact same problem / error:

[esri.views.layers.2d.features.support.AttributeStore]
e {name: "mapview-attribute-store", message: "Encountered an error during client initialization", details: e}
details: e
details: undefined
dojoType: "cancel"
message: "Abort job: worker closing"
name: "AbortError"
message: "Encountered an error during client initialization"
name: "mapview-attribute-store"

It just loads in an infinite loop. Did you ever find out what the issue was, or find a solution?

Thanks

Is there a solution to the bug? We have this problem too.

Not yet, apparently ESRI doesn't want to admit it exists or offer a proper solution. This might be related to the Port Closed Error that I also get from time to time. It would be nice if ESRI actually responded!

Hi all,

Sorry for the lack of response on this. If you are experiencing this issue, are you able to provide a link to a repro on codepen? Are you seeing this in IE only or in other browsers?

Re: Mapview Attribute Store errors going to browser console [infinite loop]

AndrewMurdoch1 — Mon, 13 Jul 2020 17:51:35 GMT

Thank you for the reply.

I don't have one handy, but I might be able to build on later tonight, I can't replicate this error with any consistency but it seems to be something in the dojo.lite library. I've experienced this on Firefox, Chrome and Brave, I don't run IE, and it happens on Linux, not sure about Windows.

It might be related to this error, which I run into more frequently:

Thanks

Strange. I actually use Linux + chrome for my daily driver but have not yet seen this -- if you are able to provide me a repro I can take a look at this personally. The error is related to setting up the shared memory region that eventually gets pushed to the GPU (via a texture) to pass per-feature information (visual variables, filter states, etc). Does this happen when loading?

Yes, it's always well loading.

In our use case we're stacking multiple GIS layers on top of each other which are rendered from WKT parsed into GeoJSON, I'll see what I can do to get you a repo that fails on my local system and if I can run into this issue I'll try to grab a HAR capture.

Thanks!

We haven't ran into this for the last few days, if we do I'll try to log it.

Thanks Andrew Murdoch‌, I'll be looking out for this as well.

Good Day

This issue disappeared for months but now it's popping up, but I can't seem to figure out any pattern. Would it be possible to edit the error message to show what's happening to help debugging, or catch the error in dojo-lite and discard it? I haven't been able to make a source repo that demonstrates the problem.

Thanks

I'm going to try getting a HAR capture, if I do I'll attach it.

Andrew Murdoch‌ do you see any adverse affects in your apps when you see the above error (i.e., the "infinite-loop" bug in the OP), or just the error?

Likely this is a race that has to do with a layer being added/removed very quickly (probably with 100 ms of being added). When you create a FeatureLayer, that spins up a connection to a worker which communicate over a message port. The error "Can't invoke, port is closed" coming from the AttributeStore means that while the worker was trying to setup the shared memory region (which happens immediately when the connection is established), the connection was closed. We can potentially move this error behind a flag, as this likely shouldn't have any adverse consequences.

Does this sound about right for your case? Does your app add/remove a layer very quickly?
