Web UI issue after trying to watch large files

[waip2Ohng9oh]

Steps to reproduce

1. Upload large .txt file, i.e. > 2 GB
2. Open the file in the web UI with inline viewer
3. Error message dialogue appears telling that the file is too large to view
4. Close dialogue
5. Date of the file is incorrect

Expected behaviour

Show the correct date

Actual behaviour

shows 50 years. Probably date is not set, defaulting to 1/1/1970 and rounding up

Are you using external storage, if yes which one: local

Are you using encryption: no

Are you using an external user-backend, if yes which one: LDAP

@waip2Ohng9oh Is the file modification date on the storage also modified? Can you please check that?
And is the web UI ok again after refresh or does the wrong info persist?

[waip2Ohng9oh]

Hi

On storage the timestamps are still unchanged and show the expected time. After reload the timestamp is correct.

Seems to be an issue with some javascript
