Scene service missing root node

CyrusBlankinship1 — Mon, 02 Apr 2018 18:22:00 GMT

I'm attempting to share a multipatch scene layer from Pro into AGOL. However, I'm getting an error from the Job Queue stating 'Unknown map tile cache creation status returned'.

When I attempt to open the layer in the scene viewer, I'm getting the error 'Scene service is missing root node'.

A few other notes:

the layers WKID is 4326 (GCS WGS 1984)
there are ~30,000 features

When you add a scene layer still being cooked or if the creation failed or if you open a web scene or open a web scene while the scene layer is still being cooked/creation failed you will see this root node error.

Were you able to publish your data?

Was anyone ever able to find a solution for this issue? I too am having a similar error.

Did you publish the scene layer from Pro and did you see the job complete on the jobs pane of Pro if Pro was used?

I believe the issue was with my data. Some how I had a record in the attribute table of my feature class that did not have any geometry associated with it. My best guess is this causes an error when trying to create the scene layer cache in AGOL as there would no longer be a 1 to 1 relationship between the Hosted Scene Layer and the Hosted Feature Layer.

It is still problematic that I cant find a way to check the status of a map cache that is being created on the AGOL servers. This is especially true if any interaction with a scene layer that is still cooking causes the entire scene layer creation process to fail.

When publishing through Pro you have the jobs pane which will report the cache status like building, completed or a failure.

If you publish a scene layer from a feature layer in ArcGIS Online through the item details we have a job status button on the settings tab which shows you the job status while the cache is being built and for 48hrs after the job has completed or failed.

Clicking on Job Status in the image below

Will present you with the Job ID and time which can be helpful for us to determine any backend issues.

I am also facing strange errors while trying to share a web scene from ArcGIS Pro 2.4.

The error in the jobs is the following: "Unknown map tile cache creation status returned"

This seems to happen only for some Scene Layers in my scene, while others are shared succesfully.

Here is a printscreen of my "Job Queue" panel to give you an idea.

Those failed-to-publish WSLs (WSL1, 2, 3, 5) are not that different from those which were published succesfully.

The WSL5 in particular, is part of a group layer containing the other layers published succesfully (WSL4, 6, 7, 8, 9, 10), which were converted from a IFC with the Data Interoperability together with the failing WSL5.

Also, I recall having published this same Scene without problem.

Is the Unknown map tile cache creation status returned error related to a network problem?

I also recall once in a while having problems in publishing Web Scenes from Pro which were solved by republish the same Scene without modifications after a while.

Apparently those four Web Scene Layers with errors in the Jobs panel are present in my contents in AGOL. I tried to rebuild the cache for one of them in the item's detail page -> Settings.

It failed the first time but it completed the second.

One (the last one) failed to revuild the cache. Here is what you are asking for:

Could you try republishing the failed layers again from Pro. I think possibly there could be an issue with the Feature layer and that is why it failed. Also if you can share the SD file for one of the failed layers with me I can take a look as well.

Hi Russell Roberts‌,

I've already solved the problem by re generating the cache from AGOL, so I didn't do the sharing from Pro again to see if that would have worked.

Anyway, here is the link to the sd file of one of the layers which failed to publish.

Thanks.

I am also having this issue when trying to publish multipatch features from Pro 2.4 to a web scene. I have tried the suggestion from Alessandro to rebuild the cache in AGOL, but that did not work and the layer still fails to draw ("Scene service is missing root node.").

My issue is exactly as described by Alessandro, but the presented solution is not working.

The only workaround that I have discovered so far is that if I delete all of the published layers from AGOL and try publishing from Pro again, sometimes (~1 / 3 times) it works correctly.

I get this for one project when I use a z-enabled point feature with elevation set at the geometry z value. I buffered the point and extruded it and I can see the extrusion but it would be nice to place the point at its correct elevation.

Any way to do this?

Thank you,

Randy McGregor

I'm getting this today on a web scene that did not have this problem in the past.

Re: Scene service missing root node

RussRoberts — Wed, 22 Jul 2020 14:51:33 GMT

Where did you publish the scene service from?

Re: Scene service missing root node

RandyMcGregor_Home — Wed, 22 Jul 2020 19:03:57 GMT

ArcGIS Pro

It looks as though I am having no luck with anything that is not a polygon as a 3D layer. Point layers with a z value are throwing this error.

Thanks,

Randy

Re: Scene service missing root node

RussRoberts — Wed, 22 Jul 2020 20:11:29 GMT

Do you see if the publishing was completed or if an error was reported in the Jobs pane of Pro?

Re: Scene service missing root node

RandyMcGregor_Home — Thu, 23 Jul 2020 12:17:02 GMT

No errors during publishing at all. The job was definitely finished. It was published a couple weeks ago.

The problem appears to happen with point features in the 3D layers group. I can put point features in the 2D layers group and they'll drape on the surface, which is fine, but if I want to z-enable point features and put them in the 3D layers group, I get this error every time (the error happens when the scene is opened in the Portal, not during publishing). No problem whatsoever with extruded polygons, so I'm buffering points and creating "tubes" a lot.

Thanks,

Randy McGregor

The errors would be in the Jobs pane and would report if the cache build was successful. This error ususally means the cache failed to build and the error would be reported there for the scene layer. Can you share the Pro project and I can look into it?

Re: Scene service missing root node

RandyMcGregor_Home — Thu, 23 Jul 2020 14:04:56 GMT

Thank you,

I am unable to share the data. It is confidential. I checked the job queue and it says caching was completed. "Cache status: succeeded." It just refuses to open in a scene. There may be something amiss with our configuration.

Re: Scene service missing root node

RandyMcGregor_Home — Thu, 23 Jul 2020 14:07:46 GMT

If I put the same feature class into "2D Layers" it publishes fine.
