Although the configuration of my Nextcloud may be different, I have found that Scanning all files using the files:scan command in occ floods my Nextcloud log with a variant of this error. Seeing how the community could provide valuable information to any developers folowing this topic, it would be great if @Oriann updates the original post by providing the versions of the software used in his installation, to help reduce the number of these errors.
Here are the details of my installation:
Background:
The Nextcloud package is installed, using an archive file, on a shared hosting server with some folders connected to external storage.
Nextcloud version: 18.0.4, 18.0.6 => 18.0.7
Operating system and version: Ubuntu 18.04
Apache or nginx version: Apache 2.4.29
PHP version: 7.4.3
The issue you are facing: refer to the first paragraph of my post in this topic.

N.B. Agree with @andyp that the errors persist when upgrading to PHP 7.4 from PHP 7.2, while using a point release following Nextcloud 17.0.1
