Hi @keithlaikf,

This error occurs because of PHP 7.4 depreciations. If possible, use PHP 7.3. If not possible, you will have to edit line 53 of the file vendor/laravel/framework/src/Illuminate/Http/Resources/DelegatesToResource.php to be:

return isset($this->resource[$offset]);

You can use the exclude-from-classmap in your composer.json and then include your own version of the \Illuminate\Http\Resources\DelegatesToResource class (be sure to match the namespace!), or you can patch it: https://tomasvotruba.com/blog/2020/07/02/how-to-patch-package-in-vendor-yet-allow-its-updates/

Edit: Nope, you can't patch it. The Workshop module is locking symfony/yaml to v3, but the patch method requires v5.

Here's how I did it:

...
    "autoload": {
        "classmap": [
            "database/seeds",
            "database/factories"
        ],
        "psr-4": {
            "App\\": "app/",
            "Modules\\": "Modules/",
            "Illuminate\\Http\\Resources\\": "overrides/Illuminate/Http/Resources"
        },
        "exclude-from-classmap": [
            "vendor/laravel/framework/src/Illuminate/Http/Resources/DelegatesToResource.php"
        ]
    },
...

Then I copied vendor/laravel/framework/src/Illuminate/Http/Resources/DelegatesToResource.php to overrides/Illuminate/Http/Resources/DelegatesToResource.php and changed line 53.
