Sets the number of retries left to execute external tasks by id asynchronously. If retries are set to 0, an incident is created.

Method

POST /external-task/retries-async

Parameters

Request Body

A JSON object with the following properties:

Name	Description
retries	The number of retries to set for the external task. Must be >= 0. If this is 0, an incident is created and the task cannot be fetched anymore unless the retries are increased again.
externalTaskIds	The ids of the external tasks to set the number of retries for.
processInstanceIds	The ids of process instances containing the tasks to set the number of retries for.
externalTaskQuery	Query for the external tasks to set the number of retries for.
processInstanceQuery	Query for the process instances containing the tasks to set the number of retries for.
historicProcessInstanceQuery	Query for the historic process instances containing the tasks to set the number of retries for.

Result

A JSON object corresponding to the Batch interface in the engine. Itsproperties are as follows:

Name	Value	Description
id	String	The id of the created batch.
type	String	The type of the created batch.
totalJobs	Number	The total jobs of a batch is the number of batch execution jobs required to complete the batch.
batchJobsPerSeed	Number	The number of batch execution jobs created per seed job invocation. The batch seed job is invoked until it has created all batch execution jobs required by the batch (see `totalJobs` property).
invocationsPerBatchJob	Number	Every batch execution job invokes the command executed by the batch `invocationsPerBatchJob` times. E.g., for a process instance migration batch this specifies the number of process instances which are migrated per batch execution job.
seedJobDefinitionId	String	The job definition id for the seed jobs of this batch.
monitorJobDefinitionId	String	The job definition id for the monitor jobs of this batch.
batchJobDefinitionId	String	The job definition id for the batch execution jobs of this batch.
tenantId	String	The tenant id of the batch.

Response Codes

Code	Media type	Description
200	application/json	Request successful.
404	application/json	Returned if the task does not exist. This could indicate a wrong task id as well as a cancelled task, e.g., due to a caught BPMN boundary event. See the Introduction for the error response format.
400	application/json	If neither externalTaskIds nor externalTaskQuery are present or externalTaskIds contains null value or the number of retries is negative, an exception of type `InvalidRequestException` is returned. See the Introduction for the error response format.
