Swapping source layers on the hosted feature layer view breaks viewer access.

解决办法

• Use the REST API to access the hosted feature layer view 'deletefromDefinition' and 'addToDefinition' endpoints to drop and re-add layers, setting the correct layer ID.
• Use the Python API to alter the content item's data JSON to reflect the current layer ID. This does not correct dependent maps or apps that already use the old layer ID.
• Swap the source layer using the workflow outlined here: https://doc.arcgis.com/en/arcgis-online/manage-data/swap-view-source.htm.
