# EventRecord

A streaming event record. Records are newline-separated as per the chunked output standard. Each record will contain a 'state' field and potentially a 'data' field. When the state is 'RUNNING', the 'data' field will be valid. In all other states, the 'data' field will be null.

**Type**: `object`
