Overwriting a feature layer that has 'Keep track of changes to the data' enabled clears the change logs and existing 'layerServerGens' value in the layer's service definition.

解决办法

To restore the layerServerGens information, follow these steps:

1. In the item's settings, disable 'Keep track of changes to the data' (add, update, delete features)" in the Editing section and save the changes.

2. Once saved, re-enable this setting again and save the layer. The layerServerGens information will reappear.
