I’m starting work on a custom Strapi upload provider for box.com, whose SDK is in TypeScript. When I run my server I get the following error:

TypeError: provider.init is not a function at createProvider (/Users/erikmadsen/Documents/Projects/SBM/sbm-strapi/node_modules/@strapi/plugin-upload/server/register.js:60:37)

Provider is at providers/strapi-provider-upload-box/index.ts

Builds to dist/providers/strapi-provider-upload-box/index.js

package.json

"devDependencies": {
    "ajv": "^8.17.1",
    "strapi-provider-upload-box": "file:./dist/providers/strapi-provider-upload-box"
  },

plugins.js

module.exports = ({env}) => ({
    upload: {
        config: {
            provider: 'strapi-provider-upload-box',
            providerOptions: {
                clientId: env('BOX_CLIENT_ID'),
                ...
            }
        }
    }
});

dist/providers/strapi-provider-upload-box/index.js

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
// providers/upload-provider-box/index.ts
const { BoxJwtAuth, JwtConfig, BoxClient } = require('box-typescript-sdk-gen');
exports.default = {
    init(providerConfig) {
        return {
            upload(file) {
                return new Promise((resolve, reject) => {
                    /* My implementation */
                });
            },
            delete(file) {
                return new Promise((resolve, reject) => {
                    /* My implementation */
                });
            },
        };
    },
};
