Getting SyntaxError: Cannot use import statement outside a module only when trying to import graphql-upload module

`` import graphqlUploadExpress from "graphql-upload/graphqlUploadExpress.mjs";

and when I use this import graphqlUploadExpress from "graphql-upload/graphqlUploadExpress.js";

`` I get Error: Package subpath './graphqlUploadExpress.js' is not defined by "exports @jaydenseric

The correct import is this:

import graphqlUploadExpress from "graphql-upload/graphqlUploadExpress.mjs";

It sounds like something about your project is incorrectly setup relating to the way Node.js ESM and CJS works together:

It's certainly not an issue with graphql-upload; I'm able to import and use the current version fine in projects.
