New Issue w/Web Maps

BrianO_keefe — Mon, 16 Apr 2018 17:44:45 GMT

So all of a sudden, a nice batch of our webmaps are crashing... but not all of the time.

They are providing the following type of error message:

"The layer, <insert name of random layer>, cannot be added to the map."

However, if you refresh, suddenly that layer loads just fine but another one won't load. But a refresh might bring back issues with the last layer or it might load perfectly?

We have checked fiddler, Google Developer Console, and the best I can tell is it keeps spouting on about a Syntax Error...

SyntaxError: Unexpected token <
at Object.b.fromJson (init.js:131)
at Object.json (init.js:84)
at r (init.js:88)
at c (init.js:103)
at d (init.js:103)
at b.Deferred.resolve.callback (init.js:105)
at init.js:92
at k (init.js:107)
at t (init.js:107)
at d.resolve (init.js:109)

I'm lost. We've troubleshot everything I can think...

If you want to take a look, here is one of the maps... ArcGIS Web Application

Hey Brian,

Are you able to share the web map?

Same issue here some 2 of my 7 maps show:

I can see nothing missing in table of content, but still don't like this message especially when multiple syncs failed and suddenly went through this morning. Health board says all fine.

Here is the original map. It has worked fine for almost a year but suddenly it stopped.
ArcGIS Web Application

Then I went in and recreated the MXD, published a brand-new REST service from it, created brand-new AGOL objects (feature layers) and a new AGOL web map, opened WAB and added the map, then published the brand new version of the above map as this:

Brian O'keefe‌ - have there been any recent changes to the server? It appears requests are sometimes returning a web adaptor error:

Hi Felix,

Can you share your web maps? Also, please get in contact with technical support so we can look into this further.
