EN

public string $filename;
public mixed $errorlist = [];
public bool $showLoadSequence = True;

public function getError()
{
    // check if job table is empy
    if (!DB::table('jobs')->exists() && $this->showLoadSequence === True) {
        $this->showLoadSequence = False;
        // call to action!
    }

    $errors = ValidationResult::where('file_name', '=', $this->filename)
        ->where('isValid', false)
        ->get();

    if (count($errors) !== count($this->errorlist)) {
        $this->errorlist = $errors;
    }
}

public function render()
{
    return view('livewire.error-loader');
}

<div wire:poll.3s="getError">
