You are sharing a web feature layer with sync enabled, but the layer or stand-alone table has a field data type that is not supported for synchronization. To share the web layer with sync enabled, the field must be hidden.
The following field types cannot be used with the sync capability:
- Big integer
- Date only
- Time only
- Timestamp offset
The <value> parameter is layer or stand-alone table.
Solutions
Do one of the following:
- Hide the field.
Hover over the analyzer message. Click the Options button
that appears and click Open Fields View. In the Visible column, uncheck the check box that corresponds to the field. On the Fields tab, in the Manage Edits group, click Save 
.Note:
Hidden fields cannot be used for authoring, such as configuring definition queries or labels on a layer.
- Disable sync.
Click the Configuration tab and if necessary, click Configure Web Layer Properties
next to Feature. Under Operations, uncheck Enable Sync. - Use the Convert Temporal Field tool to convert the field to a type that supports synchronization such as the date field type. Hide the field after it is converted.
