s3Options: {
accessKeyId: env("AWS_ACCESS_KEY_ID"),

sizes: [
{

},
{
name: "original",
},
],
},
},
});

src/extensions/upload/strapi-server.ts

import imageOptimizerService from "strapi-plugin-image-optimizer/dist/server/services/image-optimizer-service";

module.exports = (plugin) => {
plugin.services["image-manipulation"] = imageOptimizerService;
return plugin;
};
I uploaded images , but images not get converted to desired format

Please suggest , Anything wrong in the code
I having doubt related to src/extensions/upload/strapi-server.ts .. this should be .js/.ts
