Query the activity endpoint without an itemid filter doesn't return any results

Describe the bug

As per title, it should be possible to query the activities endpoint without any itemid filter.

What would be the expected outcome? All activities from all spaces? This can get quite a lot.

[AlexAndBear]

User facing outcome, or what is your question? If you have performance concerns: Later we will have server site pagination on top of that

[kobergj]

No. The question is what do you expect to get when you query the activity endpoint without an item- or spaceid?

[AlexAndBear]

To get activities on all locations (spaces)
