Error Message

The method to be called is not callable or is an async method or a generator.

Description

This error code is reported when you attempt to call an API of an incorrect type on a registered object.

Error Message

Timeout exceeded.

Description

The lockAsync API fails to acquire a lock within the specified period.

Possible Causes

A deadlock occurs somewhere.

Description

A task within the waiting list of the asynchronous queue is discarded.

Possible Causes

When the number of tasks executed by calling asyncRunner.execute exceeds the capacity of the waiting list, the earliest task in the list is discarded.

Solution

1. Increase the capacity of the waiting list.
2. Locate the cause of slow task execution and check the task execution logic.

10200055 Asynchronous Queue Task Canceled

Error Message
