Php 7.4, composer 1 unexpected '$conversion' (T_VARIABLE), question.

[audetcameron]

When deploying to my staging server I get this infinite loop in the error logs / maxes out the server.

, unexpected '$conversion' (T_VARIABLE), expecting ')' {"exception":"[object] ///vendor/spatie/laravel-medialibrary/src/MediaCollections/Models/Media.php

I am running laravel forge with both CLI and site pointed to PHP 7.4.24 (cli) (built: Sep 23 2021 21:35:51) ( NTS ).
On my forge dev server, no issues running PHP 7.4.15 (cli) (built: Feb 23 2021 15:12:26) ( NTS ).

My question is, the only difference between the two (other than minor PHP versions) is staging is running composer v1 and dev is running composer v2. Would the composer version be causing the issue?

Laravel 7
Spatie Media library 8

"spatie/laravel-medialibrary": "^8.10",
"laravel/framework": "^7.29",

Thanks in advance.
