Can't download Maatwebsite Excel

I'm trying to create an Excel but it won't download correctly or at all. This is my full code from the front, in the vue method I originally was going to use Inertia to make the request but had the same problem so I tried $http instead but no luck, I'm not sure if that makes a difference.

Request from frontend using Vue

export_excel(val) {
    this.$http.post(`/surveys/surveys/${this.$page.props.survey.id}/excel_report`, {
        filters: this.filters
    });
},

Routes

Route::prefix('surveys')->group(function () {
            Route::post('/{id}/excel_report', [SurveyController::class, 'get_excel_report']);
        });

Controller

public function get_excel_report(Request $request, $id)
    {
        $survey = Survey::findOrFail($id);

        $result = SurveyReportDetail::with(
            'question',
            'section',
            'report.user',
            'report.survey.sections.questions',
            'report.sale_point.format.chain.channel'
        );

        if ($request->get('filters.images')) {
            $result->whereHas('report.survey.sections.questions', function ($query) {
                $query->where('response_type', '!=', 'image');
            });
        }

        $result->whereHas('report', function ($query) use ($request, $id) {
            //sale_point filter removed for length
           
            if (!empty($request->get('init_date'))) {
                $query->where('date', '>=', $request->get('init_date'));
            }

            if (!empty($request->get('end_date'))) {
                $query->where('date', '<=', $request->get('end_date'));
            }

            //supervisor filter removed for length
        });

        return (new SurveyReportGeneralExport($result->get()->toArray()))->download('test.xlsx');
    }

And Finally the Export File

class SurveyReportGeneralExport implements FromArray, WithHeadings
{
    use Exportable;

    protected $items;

    public function __construct(array $items)
    {
        $this->items = $items;
    }

    public function array(): array
    {
        $data = [];

        foreach ($this->items as $item) {
            $data[] = [
                $item['report']['date'],
                $item['report']['latitude'],
                $item['report']['longitude'],

                !empty($item['report']['sale_point']['format']['chain']['channel']['description']) ?
                    $item['report']['sale_point']['format']['chain']['channel']['description'] : '',

                !empty($item['report']['sale_point']['format']['chain']['description']) ?
                    $item['report']['sale_point']['format']['chain']['description'] : '',

                !empty($item['report']['sale_point']['format']['description']) ?
                    $item['report']['sale_point']['format']['description'] : '',

                !empty($item['report']['sale_point']['name']) ?
                    $item['report']['sale_point']['name'] : '',

                $item['report']['user']['name'],
                $item['section']['description'],
                $item['question']['description']
            ];
        }

        return $data;
    }

    public function headings(): array
    {
        $headings = [
            'FECHA',
            'LATITUD',
            'LONGITUD',
            'CANAL',
            'CADENA',
            'FORMATO',
            'PUNTO DE VENTA',
            'USUARIO',
            'SECCION',
            'PREGUNTA',
            'RESPUESTA'
        ];

        if (Survey::findOrFail($this->items[0]['report']['survey']['id'])->pluck('is_evaluation')) {
            $headings[] = 'NOTA';
        }

        return $headings;
    }
}

What am I doing wrong?

This is what I see when I try to download the Excel file https://ibb.co/gyJ7khP
