[Help] Database issues

When I added the magic mission, I kept prompting this error！

Prompt:DbManagerFun.cpp, 1210.

Does anyone know how to solve it? Thank you

New problems：
The pink balloon with +50 attack power has a duration of 3 days when used, but when I log in to the client again, the persistence time becomes 1 hour, does anyone know what caused it? Thank you
