Waiting for external tasks that correspond to the `Topic` configured in
the connected ProcessCube Engine for processing.

## Configs

: name (string) : The name of the node
: workername (string) : The optional name of the worker otherwise it will be generated with the pattern 
    nodered:NODERED_NAME-host:HOST_NAME-pid:PID-id:ID of the node
: engine (engine-node) : The ProcessCube Engine to connect to
: topic (string) : The topic of the external task
: workerConfig (object) : The configuration for the worker

### workerConfig

- workerId (string): The id of the worker
- lockDuration (number): The duration in milliseconds the external task is locked for execution
- maxTasks (number): The maximum number of tasks that can be fetched at once
- longpollingTimeout (number): The duration in milliseconds the external task is locked for execution
- payloadFilter (Req-Expression): The filter for the payload of the external task

## Outputs

: payload (string) : The payload the external task was started with.
: task (object) : The external task object
: flowNodeInstanceId (string) : The unique identifier of the external task, which is needed to complete the task

### Details

-   To finish the external task the `externaltask-output` node is required.
-   For handling a error while executing a flow as external task the `externaltask-error` node is required.
