Can not edit text files

[djermann]

Expected behaviour

Being able to edit .txt and .md files on the iOS App.

Actual behaviour

Clicking on a .md or .txt file gives a "File not found" error in the frontend and the following error in the back-end:

PHP message: [owncloud][files][3] {"Exception":"OC\\Encryption\\Exceptions\\DecryptionFailedException","Message":"Can not decrypt this file, probably this is a shared file. Please ask the file owner to reshare the file with you.","Code":0,"Trace":[{"file":"/var/www/nextcloud/lib/private/Files/Stream/Encryption.php","line":507,"function":"decrypt","class":"OCA\\Encryption\\Crypto\\Encryption","type":"->","args":["*** sensitive parameters replaced ***"]},{"file":"/var/www/nextcloud/lib/private/Files/Stream/Encryption.php","line":302,"function":"readCache","class":"OC\\Files\\Stream\\Encryption","type":"->","args":[]},{"function":"stream_read","class":"OC\\Files\\Stream\\Encryption","type":"->","args":[43]},{"file":"/var/www/nextcloud/lib/private/Files/Storage/Wrapper/Encryption.php","line":217,"function":"stream_get_contents","args":[null]},{"file":"/var/www/nextcloud/lib/private/Files/Storage/Wrapper/Wrapper.php","line":245,"function":"file_get_contents","class":"OC\\Files\\Storage\\Wrapper\\Encryption","t" while reading response header from upstream, client: ***removed***, server: ***removed***, request: "GET /apps/files/directEditing/pPSYtD6C5Wc5sWjrzaWQFEMjJwPZeYKroSEELGkRKPSBffGYWWWWH3TRKrSFKgdQ HTTP/2.0", upstream: "fastcgi://unix:/var/run/php-fpm.sock:", host: "***removed***"

Steps to reproduce

1. Click on a .md or .txt file in the iOS app.

Reasoning or why should it be changed/implemented?

iOS version

13.5.1

App version

Server configuration

Operating system:
Debian 10
Web server:

Database:

PHP version:

Still Not fixed after ios app and Server update

This is very critical for me. All my notes are txt files stored in nextcloud (much better for privacy than icloud notes, but it must work!).
It would be great to have a way to sync notes with one of the next cloud directories, or have an nextcloud app just for txt editing. Specially for vim/terminal users.

Do you have install on server Nextcloud Text ?

[jasondaigo]

Do you have install on server Nextcloud Text ?

i sure do. works in browser.but not in iphone app.

@marinofaggiana I am answering on behalf of djermann and yes, we have the Nextcloud Text app installed on the server
- text: 2.0.0

[brunoschroeder]

Please, Next Cloud Team.

Do you advise the downgrade of text plugin to make it work whilst you bugfix ?

Alternatively, could you release 2.0.1 rolling back some bogus code so that the main functionality in NextCloud works, please ?

This bug has also been reported now on text plugin:
nextcloud/text#978

Are you using server side encryption with user keys?

[CamZie]

@juliushaertl that is correct, we are using server side encryption with user keys.

[jasondaigo]

i had text version 1.1.1 (running nc17) installed, even though this version does not seem to exist for download on github (talking about https://github.com/nextcloud/text). i then downgraded to version 1.0.1, and the issue remains. then updated to the offered 1.0.2 text version. Issue still present. tested with appstore and testflight version today. no difference. im clueless now. i hate myself for touching the update button (once again).

[juliusknorr]

So with user keys there is no way we can edit this as of the way direct editing currently works in an anonymous session (similar to collabora or onlyoffice), so there is not much we can do here. However the clients should of course not offer editing then. For that see nextcloud/server#22423

[jasondaigo]

I do not use server side encryption with user keys by the way

[juliusknorr]

Then please open a separate issue as all error messages and log entries provided here are referring to encryption.

[juliusknorr]

Ah actually it could be nextcloud/text#577 is missing a backport if you are still on nextcloud 18.
