Request Body Format for Replicate tasks

If the task option (see above) is RESUME_PROCESSING_FROM_TIMESTAMP, then use the following format:

JSON File Format:

Inline Format:

"{\"cdcposition\":\"timestamp\"}"

Example:

"{\"cdcposition\":\"2017-03-07T11:19:03\"}"

If the task option (see above) is RECOVER_USING_CHECKPOINT_STORED_ON_TARGET, then use the following format:

Errors

All of the general errors as well as the errors listed in the table below.

Error responses
Error	Message	Description
AEM_TASK_ALREADY_RUNNING	Replicate task {task} on server {server} is already running.	The task cannot be run because it is already running.
AEM_TASK_IN_RECOVERY	Replicate task {task} on server {server} cannot be run as it is in a recovery state.	The task cannot be run because it is in Recovery state.
AEM_WRONG_OPTION_FOR_CDCPOSITION	Replicate task {task] on server {server} cannot be run with cdcposition {position} and option {option}. Change the option to RESUME_PROCESSING_FROM_TIMESTAMP or RECOVER_USING_CHECKPOINT_STORED_ON_TARGET.	When the option Tables are already loaded. Start processing changes from Timestamp is selected in the Advanced Run Options dialog box for a task, the option sent to the API must be RESUME_PROCESSING_FROM_TIMESTAMP.
AEM_CDC_POSITION_ERR_FORMAT	The cdcposition parameter value for Replicate task {task} on server {server} is not in the correct format ('YYYY-MM-DDThh:mm:ssZ').	The cdcPosition parameter must follow this format: YYYY-MM-DDThh:mm:ssZ Parameters: task name and server name
