Layers not showing in Explorer (iOS)

KevinShirey — Tue, 03 Apr 2018 14:27:40 GMT

I have a map of water data (mains, valves, meters, etc.) that just recently stopped showing layers. I've tried updating the feature layer. I've completely removed and re-uploaded the layer. I've even completely replaced the layer, map, and all files associated with the map. Nothing seems to make the layers show on explorer, even though they show in every other viewer (Pro, Web Map, Web App).

The only error I can see is when I open the legend in the explorer app. All the layers show "Invalid JSON".

Hi Kevin,

I wonder if you are running into an issue we recently identified? We have seen some "invalid json" errors when there is a Domain defined in the services you are rendering, that do not have any values specified. When there are no coded value domains, we don't handle this case well.

If this is your case, there is a Workaround in the meantime.

First thing

1) Lets identify if this is in fact your issue. Can you inspect the JSON of the services you have in your map

- here is an Example of the JSON endpoint you should be inspecting using one of our sample services (https://sampleserver6.arcgisonline.com/arcgis/rest/services/CommercialDamageAssessment/FeatureServer?f=pjson )

- Search for some text that looks like this "codedValues": []"

- essentially that text is showing an empty array of Values

- An example of JSON might look like this

{

"name": "MATERIAL",

"type": "esriFieldTypeString",

"alias": "MATERIAL",

"domain": {

"type": "codedValue",

"name": "MATERIAL",

"codedValues": []

2) Workaround: If you have found such a case, here are the workaround steps

- Identify which Geodatabase domains have this issue in your source geodatabase.

- Add a minimum of 1 coded value to the domain

- Republish the services.

Is this your case? If not (or even if so), if you can share your webmap with me, I can help identify what's up.

Thanks,

Heather

Oops! the example Service endpoint should have been to one of the layers

So https://sampleserver6.arcgisonline.com/arcgis/rest/services/CommercialDamageAssessment/FeatureServer/0?f=pjson

That worked! Thank you so much, Heather!

Great Kevin!
We'll work to get this into the software as soon as we can.

Hi Heather,

I am experiencing a similar problem. I have a web map with hosted feature services of hydrants, valves, and mains. The mains layer shows the invalid json error in the explorer app, but the hydrants and valves appear correctly. All three services were published from the same database through pro. I've checked for empty domains as you mentioned above but there aren't any.

Thanks,

Gavin

HeatherMcCracken — Fri, 13 Apr 2018 18:12:35 GMT

Okay Gavin,

Lets sort it out.

The `invalid json` is a bit of a catch all generic message - so its very likely something else that is up.

Are you able to share your webmap with me? or one of the services you are trying to display?

Can you email me directly at hmccracken@esri.com (and cc Explorer4ArcGIS@esri.com ) and we'll get to the bottom of it. If the content isn't shared with everyone, you can share the content directly with my user 'heather_nitro` by following these blog instructions: https://www.esri.com/arcgis-blog/products/arcgis-online/uncategorized/sharing-content-privately-between-organizations/

Best,

Heather,

I am going to join the party. I tried the correct answer remedy but to no avail. Would appreciate some help as well.

Thanks in advance,

Larry

Great Gary - yes please do.

Can you share the map with me so I can have a look?

Thanks Larry - i joined the group just now.

I can open both maps, but I don't have access to some of the layers you have in the map (like CK_GPS). I only have access to the "Service_Area_Boundary - .." layers - but all others getting the permissions errors.

Can you share the layers with that group as well?

Re: Layers not showing in Explorer (iOS)

LarryMasters — Thu, 31 May 2018 11:30:15 GMT

Done, Sorry about that.

Re: Layers not showing in Explorer (iOS)

HeatherMcCracken — Thu, 31 May 2018 13:56:52 GMT

Thanks Larry,

I was able to open the Manholes map - and am able to reproduce the Invalid JSON error. It seems to be a new case, so i am investigating what's up and will get back to you on this.

I still don't have access to the Layers in the 2nd map - WKUD

Can you check the sharing on those layers as well? And I can see what's up with those?

Thanks,

Heather

Heather,

That map is OK. No worries on it.

Ok good stuff Larry - thanks. I'll keep you updated on my progress. Hopefully I'll know more soon.

Larry,

I think we've narrowed down what the underlying renderer is complaining about.

The unique value renderer is based on a Date field, and the value for the the Date field is <null>. Something down the chain does not like this.

1) I will definitely continue to follow this up, seems like a bug that we are not handling this case.

I will Chat with some other folks to find out the conditions under which the service would be published this way.

2) Try to get you moving forward and beyond this.

Can you try the following for me? In a test project, can you set the Renderer to something other than that date field (

ESRIGNSS_FIXDATETIME) ? or add a specifc Date value to symbolize on, to that to see if gets you around this issue?

I'm attempting to recreate the service as you have it -

Can you give me some details about how you've published it? email me at hmccracken@esri.com

With details like, whether using Pro or ArcMap, what versions of that etc. (if you can share a Pro package or MXD + data subset that would be great too)

"defaultLabel": "<all other values>",     "uniqueValueInfos": [       {         "symbol": {           "type": "esriSMS",           "style": "esriSMSCircle",           "color": [             255,             0,             0,             255           ],           "size": 8,           "angle": 0,           "xoffset": 0,           "yoffset": 0,           "outline": {             "color": [               0,               0,               0,               255             ],             "width": 1           }         },         "value": "<Null>",        "label": "<Null>",         "description": ""       }     ],

Wanted to get you something before the weekend - so wanted to reach out. I'll continue to look into this.

Thanks,

Heather

Heather,

Thanks for the speedy reply. Don’t worry about it today. Too close to weekend. I will take it up again Monday.

Have a great weekend,

Hi Heather,

I am currently running into issues with the explorer map not showing layers, however, I am not getting any errors with it. They just simply are not there when I load the map on explorer but I can see them when I get on the Collector app. Any suggestions?

Sarah

Hi Sarah,

Sorry you are having an issue. Is it possible you are running into the issue described here?

https://support.esri.com/en/Technical-Article/000021401

Patch to resolve: ArcGIS (Desktop, Engine, Server) Microsoft ( R ) Windows ( R ) June 2019 Security Update Compatibility Patch

fyi - here is another thread where Explorer users reported similar rendering issues here, which ended up being resolved with the patch above.

Feature layer not displaying in Explorer app, but displays in AGO

Have a look at this, and see if installing the patch and resolves the issue - Hopefully this does the trick? Let me know how it goes.

Thanks,

Heather

New here, trying to learn how to post a question. I am having similar issues with a markup layer sent to user via email not wanting to open in the Explore mobile app. It keeps asking for a log in rather than just opening the file on the saved map. they are using the free version that allows them to continue without log in.
