Couldn't read/deserialize file Underflow Issue

[fahadtaric]

Hi,

I am getting this error from two months and I don't know why. I looked into similar issues you closed but the resolution is not available yet. Can you please help us with this?

This is not a full stack trace, there is should be available a nested stack trace causing this error.

[fahadtaric]

I updated the stack trace. Is this you are looking for?

[pilgr]

what is the Paper DB version do you use? Is it reproducible for some users or 100% cases? Can you reproduce the issue?

[fahadtaric]

This issue was producing on v2.0. I upgraded to v2.6 today. This issue is hitting to 10-15% users when they newly installed the app or when they upgrade. I have tried to reproduce it but unsuccessful.

[pilgr]

Yes, the issue should be already fixed. Especially version 2.5 contained very important fixes. https://github.com/pilgr/Paper/releases/tag/2.5

[pilgr]

please reopen issue once you see it on the 2.6. thanks!

[fahadtaric]

Thank you. Hope so my nightmare goes off with the latest version. P.S I love Paper DB, you made our life easy. Thanks man.
