Unresolvable dependency resolving within Laravel - php

Question

I get the error when calling a custom function I created:
namespace App\Jobs\Device;
class UpdateUserReference {
public $installationReference;
public $userReference;
// assign payload data and installation id received to command
function __construct($bodyContent) {
$this->installationReference = $bodyContent["installationReference"];
$this->userReference = $bodyContent["userReference"];
}
}
Unresolvable dependency resolving [Parameter #0 [ $bodyContent ]] in class App\Jobs\Device\UpdateUserReference
Strange enough I never had the error before and I create my function exactly the same as for all other cases. What is wrong with the bodyContent variable I provide?
The function is called within:
public function update(Request $request) {
// Get payload from request
$bodyContent = json_decode($request->getContent(), true);
$action = $bodyContent["action"];
$installationReference = $bodyContent["installationReference"];
switch($action) {
case 'userReference':
$updateUserReference = new UpdateUserReference($bodyContent);
$result = $this->commandBus->execute($updateUserReference);
break;
}
if (!empty($result)) {
$response = [
'error' => [
'code' => 400,
'message' => "Update Error"
]
];
return $this->setStatusCode(400)->respond($response);
}
$response = [
'data' => [
'installationReference' => $installationReference
]
];
return $this->setStatusCode(201)->respond($response);
}
