Improve error handling about geonode-importer HOT 1 CLOSED

https://docs.celeryq.dev/en/stable/userguide/calling.html#linking-callbacks-errbacks

From the doc:

You can also cause a callback to be applied if task raises an exception (errback). The worker won’t actually call the errback as a task, but will instead call the errback function directly so that the raw request, exception and traceback objects can be passed to it.

This is an example error callback:

@app.task
def error_handler(request, exc, traceback):
    print('Task {0} raised exception: {1!r}\n{2!r}'.format(
          request.id, exc, traceback))

it can be added to the task using the link_error execution option:

add.apply_async((2, 2), link_error=error_handler.s())
In addition, both the link and link_error options can be expressed as a list:

add.apply_async((2, 2), link=[add.s(16), other_task.s()])
The callbacks/errbacks will then be called in order, and all callbacks will be called with the return value of the parent task as a partial argument.
