AttributeError when setting limit argument in get_activities

从 ayon_api/_api_helpers/activities.py 第 99 行附近开始，使用提供的 get_activities 脚本和 limit=10 重现该问题。跟踪为什么在调用 set_limit 之前 activities_field 为 None。完成标准是 get_activities 接受 limit 而不引发 AttributeError，并且返回的活动数量不超过请求的数量。

Is there an existing issue for this?

Description

Current Behavior

Specifying the limit argument when calling get_activities, will raise the following error :

Traceback (most recent call last):
  File "<string>", line 8, in <module>
  File "C:\Users\user\AppData\Local\Ynput\AYON\app\AYON 1.6.3\dependencies\ayon_api\_api_helpers\activities.py", line 99, in get_activities
    activities_field.set_limit(limit)
    ^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'set_limit'

Expected Behavior

It should be possible to set the limit argument.

Steps To Reproduce:

Here is a small script that you can run in the AYON launcher console or with ayon_api directly with the right env vars set up. By running it you'll get the aforementioned error.

from ayon_api import get_activities

activities = get_activities(
    project_name="projectname",
    limit=10
)

for activity in activities:
    print(activity)

Removing limit from this script and calling get_activities with project_name only will work (but be careful as it'll likely query all activities!).
