Existing Feature Service as Ouput. Objectid Error

ArmstKP — Thu, 29 Sep 2022 18:29:31 GMT

I have selected an existing feature service as an output in a big data analytic. I get this error: "Failed to find ObjectID from feature layer", even though I have an objectid field. Any thoughts/ideas?

@ArmstKP Thanks for reaching out! I would like to investigate this on my end to see if there is a workaround or a way we can better handle this on the Velocity side. Two options:

Are you able to share this layer in an ArcGIS Online group with my ArcGIS Online account, "pnasuti_iot"?
Can you provide a screenshot of the "fields" section of this layer on the service layer REST endpoint?

@PeterNasuti I have shared two layers with you. Two different versions of the same feature layer. Here is the screenshot:

@ArmstKP Thanks for sharing this layer with me! I was able to reproduce the issue and can confirm it is due to the fact that your only present layer index for this service is 221, rather than the expected 0. I wrote an enhancement/bug on our side to enhance the product to lookup layer IDs dynamically for the Feature Layer (existing) output rather than assuming the first layer index is 0.

In the meantime, I suggest the following workaround attempt:

Create new item in your ArcGIS Online content referencing your layer URL including the sublayer index
1. https://services6.arcgis.com/MU31z9HAakdc3W69/arcgis/rest/services/Velocity_ParkingLot_4326_2/FeatureServer/221
Choose to store credentials with this item
Proceed with setting your sharing/tags/information as desired
Use this new item to reference in ArcGIS Velocity when configuring the Feature Layer (existing) output

Please let me know if you have success with this workflow
