Hi,

I had a bug during upgrade from Moodle 4.2 to Moodle 4.4.

I have followed config-dist.php to set customfiletypes in my config.php. Here is my conf :

$CFG->customfiletypes = array(
     (object)array(
         'extension' => 'ipynb',
         'icon' => 'archive',
         'type' => 'application/x-ipynb+json',
         'customdescription' => 'Jupyter Notebook'
     ),
     (object)array(
         'extension' => 'py',
         'icon' => 'sourcecode',
         'type' => 'text/plain',
         'customdescription' => 'Text file'
     ),
 );

And what's in config-dist.php as example :

// $CFG->customfiletypes = array(
//     (object)array(
//         'extension' => 'frog',
//         'icon' => 'archive',
//         'type' => 'application/frog',
//         'customdescription' => 'Amphibian-related file archive'
//     )
// );

But in lib/db/upgrade.php, some patches try to do :

$custom = json_decode($CFG->customfiletypes);

As $CFG->customfiletypes is not JSON, upgrade fails.

I did not find any references to customfiletypes as JSON.

Am I missing something ?

The solution for me was to comment this part of my config then uncomment it.

Thanks
