Fix the "the diff exceeded the maximum number of files (300)" Error

[Bue-von-hon]

I encountered the following error.
It seems that when using the 'List pull requests files' API, it is possible to request more than 300 files.
I would appreciate it if this could be improved. 👍

@truongnh1992 gentle ping.

Hi @Bue-von-hon Does your PR contain more than 300 files?

[Bue-von-hon]

@truongnh1992 That's right. It's an enormous size. 😭
Since it's an upgrade of the framework for a very old project, the scale is quite overwhelming.😅
