Fire Data Provider event is failing to update the Array Data Provider

Content

We are working on editable table and add row functionality. While invoking the "Fire Data Provider event" in TableBeforeRowEditEndChain, we are getting the below error.

fireDataProviderEventAction.js:140 [VB (WARN), /vb/private/stateManagement/fireDataProviderEventAction]: No keys were specified in the event payload for the mutation operation update . Attempting to build keys from data.

log.js:22 [VB (ERROR), /vb/private/stateManagement/fireDataProviderEventAction]: update event has no keys set for the data, or the keys cannot be determined from the data, [object Object]

We have defined the Key Attributes in Array Data Provider. Also we mapped the rowKey.
