Debugs a started execution that contains an event trigger task or alarm trigger task. When the operation is called, a message body is sent to the event trigger task or alarm trigger task. After the trigger task receives the message body, the trigger task generates a new child execution.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
