Error when pushing to the server

[TomohiroOno33]

When I push to the server, I get the following error.

Validation Failed: {"resource":"CommitComment","code":"custom","field":"body","message":"body is too long (maximum is 65536 characters)"}

What does this mean?

This problem has been solved.
The problem was caused by a large number of files, which exceeded the number of characters the system could display.

We solved it by deleting the unused files, but this may become a bigger problem in the future.
Is it possible to fix this problem on the server side?
