Modify Task logic

Allows to modify (update) task in other available process.

There are two required requirements for modifying tasks via Modify Task logic:

• task must be in node with Waiting for Callback or Set State logic
• specify correct task reference in Modify Task logic

Task reference can be specified with:

• any system parameter of the current process. For example, {{root.ref}} or {{root.task_id}}
• any other parameter of the current task {{parameter_name}}
• constant. For example, config, ref etc.

Nodes in the gray box are added automatically for error handling.

Basic settings

Process - selection of a process for copying from "tree of folders". It can be found by its name or its ID or using the {{conv_id}} (parameter of the task).

Reference - the reference of a new task that is created in another process.

New task reference can be specified by:

• any system parameter. For example, {{root.ref}} or {{root.task_id}}
• any other task parameter {{parameter_name}}
• constant. For example, config, ref etc.

Copy all parameters - this option gives a possibility to copy all parameters to a new task.

Please note!

If both tasks have a parameter with the same name, parameter value will be updated by Modify Task.

Parameters that were not in the updated request will be added there

Parameters

Button + Add "key-value" adds new parameter

Key - parameter name
Value can be specified by:

• constant
• {{parameter_name}} from task which name will be pasted
• any system parameter of the current process. For example, {{root.ref}} or {{root.task_id}}

If Copy all parameters flag is enabled, it is not required to add new parameters.

Otherwise be sure to add at least one parameter.

Additionally

Alert when there is tasks queue

Critical amount of tasks in the node.

Learn more about how it works here.

Limit the time of the task in the node

Time interval value at which task will go further through process in case if Copy task logic does not reply.

Synchronous callback

Synchronous callback - this option gives a possibility to modify tasks synchronously.

It means that tasks will be updated sequentially - strictly one after another (in course).

Please note! If you modify one task at the same time, an error duplicate_callback will occur.

Types of error

Internal system error when copying

Not found task

There is no task with specified reference in the process.

Incorrect parameters

Failed to validate one of the parameters.

Failed to convert parameter

For example, you parameter type is Number, but value is string or parameter is missed.

Inactive process

Process must be in the Active state.

Access is denied

User must have Task management access to copy task.

Task size overflow

Maximum allowed size - 128 Kb.

Duplicate modification of the task

It appears only with the flag turned on Synchronous callback. The new changement of the request will not be activated until the previous one finishes.

Standardly if this mistake occurs the request goes to the node with the logic Delay for the second try in 30 seconds..

No callback logic in node with the task

This error occurs if Synchronous callback is enabled.

Otherwise the result is __conveyor_copy_task_result__": "ok".
