Migration Error

Hi im trying to run a migration like this

datocms migrations:run --source=feature-branch --in-place

and receive this error

  "error": {
    "message": "Unexpected token 'export'"

this is the migration file

import { Client } from '@datocms/cli/lib/cma-client-node';

export default async function addTopics(client: Client) {
  // DatoCMS migration script

  // For more examples, head to our Content Management API docs:
  // https://www.datocms.com/docs/content-management-api

  // Create an Article model:
  // https://www.datocms.com/docs/content-management-api/resources/item-type/create

  const topicModel = await client.itemTypes.create({
    name: 'Article',
    api_key: 'article',

  // Create a Title field (required):
  // https://www.datocms.com/docs/content-management-api/resources/field/create

  const titleField = await client.fields.create(topicModel, {
    label: 'Title',
    api_key: 'title',
    field_type: 'string',
    validators: {
      required: {},

  // Create an Article record:
  // https://www.datocms.com/docs/content-management-api/resources/item/create

  const article = await client.items.create({
    item_type: topicModel,
    title: 'My first topic!',

It must be some silly bug but cannot fix it

Hello @gaston.e.coria and welcome to the community

This can be happen if TypeScript modules are not set to “commonjs”, and are set to “esnext” instead.

Could you try and replace it in your typescript configuration file, re-run npm install, and re-try the migration?

Let me know if it works
