File system settings page gives "'temporary' is not a supported key"

Same issue on all Drupal 11 projects, while Drupal 10 projects work fine. So I guess it's a Drupal 11 issue?

I've not been able to reproduce this bug on Drupal 11. Are there any modules on the site that could modify the file module's configuration?

@cilefen thanks for your quick reaction. That's really strange.

We use a couple of contrib modules, but none that affects this form.
Debugging this in ValidKeysConstraintValidator shows that the value that's being checked is:

[
  temporary => string (6) "../tmp"
]

This is the related settings.php entry, which looks fine to me:

// Temp directory path:
$settings["file_temp_path"] = "../tmp";

In the settings UI the value looks like this:

Temporary directory
../tmp
A local file system path where temporary files will be stored. This directory should not be accessible over the web. This must be changed in settings.php.

This is the backtrace:

Honestly, I have no idea so far...

We also had this problem with a website that started on D8 and was updated to D11. Workaround was removing

path:
  temporary: tmp

from the system.file.yml config file and import the config. But no idea what caused it in the first place.

I'm having the same error on drupal 11.1.3.

@rgeerolf, what is the location of the configuration file? Is it : core/modules/system/config/install/system.file.yml ??

Thanks for your reply.

@asman_amin no I mean in your own config directory. For my project that was in ../config/sync but of course that depends on your settings file/environment.

I am having the same issue on Drupal 11.1.3 site. Tried the workaround from #7 but it does not make any difference. Maybe because @rgeerolf upgraded from D8 to D11 which is why the path: temporary: tmp was already in config file.

On D10 sites it works as it should.

Subscribing for a solution!

I am returning the issue metadata.

The temporary file path is a setting and no longer config since Drupal 8.8.0.

See the changelog: https://www.drupal.org/node/3039255 → for details.

@kim.pepper that means there should maybe be an update hook in core cleaning this up?
