If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your Nextcloud installation folder

or 

Insert your config.php content here. 
Make sure to remove all sensitive content such as passwords. (e.g. database password, passwordsalt, secret, smtp password, …)

Are you using external storage, if yes which one: local/smb/sftp/...

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP config

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your Nextcloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Looks like it may have something to do with PHP 7.4.7 I went back to PHP 7.3.19 and did not get that error.

[closingin]

I can confirm this bug. I have the same error using the docker image with PHP 7.4.7.

@MorrisJobke any updates on this issue?

@MorrisJobke any updates on this issue?

Not really. I linked just the wrong ticket 🙈

[axheli]

@MorrisJobke Okay thank you for the update. Anyway we can have someone look into this please!

[axheli]

Same issue on NC 19.0.3

[toxpal]

Have exactly the same problem after updating to 19.0.3. All previous versions worked just fine.

[axheli]

@MorrisJobke Do we have an leads on this?

[RedKage]

@axheli I do have these errors in the log as well.

And also in the client

But it doesn't seem to affect Nextcloud beyond these errors.
Everythings gets deleted fine, and uploaded fine.
Or did I miss something?

[Kuphi]

Please fix asap. Also having this issue on NC 19.0.4
I have an encrypted nextcloud (encrypted for each user separately). The error occurs, when a user tries to delete a folder in a folder, that is shared with him.
It also occurs when I try to cut and paste a folder.

Based on what i can see its happening on PHP 7.4 if you downgrade to 7.3 i dont see this error, but that's not a solutions. There should be a fix of this.

Hopefully for NC 19.0.6 and 20.0.3. This error is crowding my logfiles for weeks already.

[axheli]

@MorrisJobke any updates on this issue?

Not really. I linked just the wrong ticket 🙈

Can you please unlink this since you liked it to the wrong ticket so we can get a fix for this?

[MorrisJobke]

There is no such thing as unlink. I mentioned it and then it will be shown in here. Deleting the mention also still keeps the entry in here. So not much I can do here.
