io.objectbox.exception.FileCorruptException: Corrupt DB, min key size violated: 0 #1143
Description
Activity
Reproducibility: occurred once only
That's a little problematic to work with because the stacktrace doesn't help us in this case.
If you see some way to reproduce, please let us know. Otherwise, a next upcoming version will provide validation for this error type, which might be helpful.
Edit: See also related #1090.
i get this error also,in my case ,i found another problem,some data can't been query by isNull, after that i get this error in bugly
here is the stackTrace,user already unistall the app,so i can't provide more infomation for this

Reacted by Uwe (ObjectBox)@linge123 Thanks for this!
If possible, can you send use the corrupted database file? (We have some example code on how to ask users to do this for a production app.)
Also to everyone, would it be helpful if ObjectBox included a repair mode that would delete corrupted keys and values (basically affected objects)?
Add a repair mode, that would be great。
The database contains user private information, which is best not to do so

how many data when crash happens ? i guess it may assosiate with data size , in my case it was about 50W data in one table
