rewrite existing file with buffer and fs responds with errno: -4094, code: 'UNKNOWN', syscall: 'open',

[aabaza97]

I'm using this function to check if an uploaded image matches a specified size and, if not, resize it to the desired dimensions before proceeding with the next middleware or route handler

const resizeUpload = (size) => async (req, res, next) => {
	try {
		if (!req.uploadInfo) throw errors.UnprocessableEntity('msg_no_uploads_to_process');
		const { uploadPath, filename } = req.uploadInfo;

		const filePath = path.join(uploadPath, filename);
		const image = sharp(filePath);
		const metadata = await image.metadata();

		const validWidth = metadata.width === size.width;
		const validHeight = metadata.height === size.height;

		if (!validWidth || !validHeight) {
			// resize image
			const fileBuffer = await image
				.resize({ width: 768, height: 1024 })
				.withMetadata({ density: 72 })
				.toFormat('jpg')
				.toBuffer();
			fs.writeFileSync(filePath, fileBuffer);
		}

		return next();
	} catch (error) {
		return next(error);
	}
};

It works just fine on MacOS, yet on Windows machine I get this error:

Error: UNKNOWN: unknown error, open 'C:\Users\User\Desktop\backend\core-backend\public\storage\user_model\1\vton\test\image\39294_00.jpg'

}

Note: The image to modify already exists and saved to disk.
