Other Issues

After creating a Feature Service from a workspace, the Feature Service thumbnail is blank on the ArcGIS web interface, and adding the Feature Service to a map results in an error.

Newly-created Feature Services may require some time to complete processing. Wait a few minutes and then retry.

When inserting features into an existing Feature Service layer, values supplied for the Object ID (FID) attribute are ignored.

ArcGIS always assigns the Object ID. It is not an error to supply an Object ID value when inserting features, but the server may ignore it.

When writing to an existing layer, the operation fails due to a server timeout or HTTP 500 response.

The server may be having trouble handling the size of the write operation. The AGOL Reader/Writer will automatically attempt 5 retries if an Error 500 is encountered. This is not configurable and each successive attempt has an increase in duration before the next retry.

Reduce the value of the Features Per Request advanced parameter and try again.
