[2023-05-24T11:30:54.572+09:00][ERROR][savedobjects-service.repository.point-in-time-finder] Failed to open PIT for types [tag] {"service":{"node":{"roles":["background_tasks","ui"]}}}

I was able to solve the problem myself.

I don't know the details of the process that runs in the background,
I changed the following permissions from none to all and the error stopped occurring.
