Error while trying to save "enable edits" in the Feature Layer settings page

[AlessandroValra]

I am experiencing this strange issue.

I have a Feature Layer associated with (published as) a Scene Layer.

I connect to my AGOL organization as the owner of these layers.

I published them automatically from ArcGIS Pro by sharing a web scene with a multipatch layer.

Now, I have to enable editing in my Feature Layer, but as I try to activate the option "Enable editing" (in the item detail -> Settings), and save, I always receive the error "Unable to save. Try again." (it's translated directly from Italian, the message in english could look a bit different).

I need this to use the layer inside Collector.

Any idea why this is happening?

Thanks.

The error in english is exactly Save wasn't successful. Try again later.

I changed the language settings to English to check if this was the cause of the problem but apparently it's not.

I am trying to change the settings by modifying the service definition associated with it in the REST admin API.

I went to https://services1.arcgis.com/.../rest/admin/services/[MY_LAYER]/FeatureServer?token=..., then in Add...

Here I tried changing:

   "capabilities" : " Query "

to

   "capabilities" : "Create,Delete,Query,Update,Editing,Sync"

but unfortunately I got an error 405 saying "This operation is not supported".

Moreover, inspecting the response from the dev tools when clicking the "save button" in the item details (not from REST) this is the message:

{"submissionTime":1523615946600,"lastUpdatedTime":1523615946600,"status":"Failed","error":{"code":500,"description":"Editing definition error - Pavia_WSL1"}}

I shared the resources publicly, if you want to investigate on the problem.

• Feature Layer
• Scene Layer
• Web Scene

Any help would be greatly appreciated.

Thanks.

Still fighting against this. Any suggestion? I cannot change the settings of my Feature Layer to "enable edits", because I still receive the same error when trying to save.

Ok, answered myself: multipatch feature layers cannot be edited.

From "Three Tips for Publishing Scene Layers from Feature Layers":

Note that multipatch feature layer editing is not supported so you will have to edit the data locally in Pro or ArcMap and overwrite the feature layer.
