Hello I created simple web where you can uplado three photos and then send them to backend which stores them in file system ... and when I start the server on my pc it works perfectly fine no matter how big the photos are (in terms of kb/mb), and when I take the project and put it on other pc and try to run the app there and try to send there some photos .. all the photos have maximally 768KB and if there are bigger photos they are cut and more of the photo is just black ...
anyone know how or why its happening and how to fix it?

im using formData object and putting the photos there as File and on backend im parsing them as base64

export async function POST(req: NextRequest): Promise<NextResponse> {
try {
const formData = await req.formData();

const photo01 = formData.get("photo_data_01") as string;

const photo02 = formData.get("photo_data_02") as string;

const photo03 = formData.get("photo_data_03") as string;


const parseBase64 = (base64String: string): Buffer | null => {
if (!base64String) return null;
const matches = base64String.match(/^data:(.+);base64,(.+)$/);
if (matches && matches.length === 3) {
const base64Data = matches[2];
return Buffer.from(base64Data, 'base64');
}
return null;
};

const photo01Buffer = parseBase64(photo01);
const photo02Buffer = parseBase64(photo02);
const photo03Buffer = parseBase64(photo03);

const dir = path.join('C:', 'Temp', 'photos');
await fs.ensureDir(dir);

const photo01Path = path.join(dir, ${log_id}_photo01.jpg);
const photo02Path = path.join(dir, ${log_id}_photo02.jpg);
const photo03Path = path.join(dir, ${log_id}_photo03.jpg);

if (photo01Buffer) await fs.writeFile(photo01Path, photo01Buffer);
if (photo02Buffer) await fs.writeFile(photo02Path, photo02Buffer);
if (photo03Buffer) await fs.writeFile(photo03Path, photo03Buffer);
