sharp won't work

my previous code was also broken, only actions can run under node so i had to refactor the code to take url and just return the metadata

"use node";

import { internalAction } from "./_generated/server";
import { v } from "convex/values";
import sharp from "sharp";

export const getImageMetadata = internalAction({
    args: {
        url: v.string(),
    },
    handler: async (ctx, { url }) => {
        const response = await fetch(url);
        
        if (!response.ok) throw new Error("Image not found");
        const arrayBuffer = await response.arrayBuffer();
        const buffer = Buffer.from(arrayBuffer);

        return await sharp(buffer).metadata();
    },
});

"use node";

import { internalAction } from "./_generated/server";
import { v } from "convex/values";
import sharp from "sharp";

export const getImageMetadata = internalAction({
    args: {
        url: v.string(),
    },
    handler: async (ctx, { url }) => {
        const response = await fetch(url);
        
        if (!response.ok) throw new Error("Image not found");
        const arrayBuffer = await response.arrayBuffer();
        const buffer = Buffer.from(arrayBuffer);

        return await sharp(buffer).metadata();
    },
});
