Uncaught RuntimeException: Missing "{$keyName}" for "{$className}"

[dragonfire1119]

I'm getting this error Uncaught RuntimeException: Missing "{$keyName}" for "{$className}" ever since I updated with composer.

My composer version: ^2.1
Tried 3.0.1

Not sure why you closed this - it's a bug in the getClassesMapping().

Quick solution is to check you config as "classes" mapping lacks either key or method entry for class. If you are upgrading from pre 3.0.0 dev code, then you need to ensure it looks like:

'classes' => [

	Illuminate\Database\Eloquent\Model::class => [
		'key'    => 'item',
		'method' => 'toArray',
	],
	Illuminate\Database\Eloquent\Collection::class => [
		'key'    => 'items',
		'method' => 'toArray',
	],
],

Fixed in 3.0.2

@MarcinOrlowski I closed it because I looked at the github config & copied the

Illuminate\Database\Eloquent\Model::class => [
		'key'    => 'item',
		'method' => 'toArray',
	],
	Illuminate\Database\Eloquent\Collection::class => [
		'key'    => 'items',
		'method' => 'toArray',
	],

It started working again on the 3.0 so I didn't want to waste your time.

My point is that if your report the issue then even you worked it around on your side, you should let the ticket opened for me to investigate. And even if you'd find that it was your fault then you should rather state this in comment and let the maintainer do the rest. Anyway, this time it was my bug, so thanks for the report :)
