    #1426448465 RuntimeException
    Field must not be empty

This error happened after updating from TYPO3 v10.4 when trying to edit a files
metadata in the "Filelist" module.

There was an invalid entry in the TCA of :sql:`sys_file_metadata`. In TYPO3 v10
the falsely declared div title was not displayed and ignored. In TYPO3 v12.4
this error was thrown.

Solution: Fix TCA of `sys_file_metadata`
----------------------------------------

Items in TCA `showitem` must be separated by comma `,` not semicolon `;`. A 
divider `--div--` must start with this string after the previous comma.

..  code-block:: diff

    $GLOBALS['TCA']['sys_file_metadata']['types'][1] = [
        'showitem' => $GLOBALS['TCA']['sys_file_metadata']['types'][1]['showitem']
    -        . ';--div--;My-Cool-Center,my_cool_center_enable',
    +        . ',--div--;My-Cool-Center,my_cool_center_enable,',
    ];


Unknown TYPO3 Version
=====================

Field must not be empty
-----------------------

Error in TCA configuration. E.g. in section ``types['1']['showitem']``.

Possible solution
-----------------

Fix TCA configuration. E.g. ``showitem`` string. (In my case, the value
was illegally starting with ``;;1,``.)
