Folder renaming - Error 503

[zkrechowiec]

I use TYPO3 version 12.4.22 and the extension version 2.0.1.

My problem occurs when I rename a folder, the ajax causes an error but when reloading the page, the folder is renamed. Displaying the files in this folder gives a 503 error "md5(): Argument #1 ($string) must be of typestring, null given".

In the database, in the sys_file table, the ‘identifier’ field in my file is NULL. If I fill it in manually, access to the file is OK again.
I don't have the problem every time.

Have you ever had this problem?
