Tried to create a chapter in Stream,
When I tried to create a chapter in Stream, it said, "There is not enough storage to save the chapter. Please try again with more space.
and cannot create a chapter.
■What we did
(1) Open a large movie of a certain size (1 hour and 30 minutes in length and 4 GB in capacity) in Stream.
(2) Start creating chapters.
(3) Create two chapters (up to this point, the video was created successfully)
(4) Created the third chapter and clicked the check mark. There is not enough storage space to save the chapter. Please make more space and try again. and an error message appears and the creation of the third chapter does not complete.
■What we tried
Log in as a different user who has been granted editing privileges, and create a chapter with the corresponding video.
→ The same error message appeared and the chapter could not be created.
Log in as a user with administrator privileges and create a chapter with the corresponding video.
→ Unable to create with the same error.
Log in with administrator privileges, check Sharepoint on the communication site where the video is stored, and check the "storage usage" of the site. The usage was 9% and there was no problem, but as a trial, increased the site's Sharepoint capacity limit to 200 GB.
→ The error was resolved and chapters could be created.
Increasing "storage usage" did temporarily allow chapters to be created, though,
However, it is not suitable as a flow to be continued as a future operation,
I would appreciate it if you could tell me the cause of the above error and how to resolve it.
