Hello everyone, I discovered a major bug in the external storage app.
I already send a issue #9896 on github , but no solution for this bug at the moment.
Have you encountered this bug? Have you resolved it? Did you find an alternative solution?
This bug occurs when i share a file in SFTP external storage. Editing this file becomes impossible for the user who receives this share.
I have this error message in my log file:
Error index Error: Cannot use object of type stdClass as array

The bug is very easy to reproduce:
- Adds a SFTP external storage as an administrator
- Chooses the following authentication method : user entered, store in database or
- Shares a file (can edit) in the SFTP external storage to a user
- Try to change the share (with the user which get the share)
In version 10 of Nextcloud this bug does not exist, it is from version 11 that this bug appears.
For now, here are the components that I suspect: External storage support (Nextcloud 11: 1.0.2, Nextcloud 13: 1.4.1) ? phpseclib ?
