const runMigration = require('contentful-migration/built/bin/cli').default;
const path = require('path');

const options = {
  spaceId: '<SPACE_ID>',
  accessToken:
    '<TOKEN>',
  yes: true,
};

const migrations = async () => {
  await runMigration({
    ...options,
    ...{
      filePath: path.join(__dirname, '<FILE_PATH>'),
    },
  });

  await runMigration({

  });

  await runMigration({
    ...options,
    ...{ filePath: path.join(__dirname, '<FILE_PATH>') },
  });

  await runMigration({
    ...options,
    ...{ filePath: path.join(__dirname, '<FILE_PATH>') },
  });
};

migrations();

Steps to Reproduce

Run the script in the console

Context

I am unable to run the migration scripts in order. The error that is provided is not very helpful and seems to be an internal application error.

Environment

Node Version: 9.11.1
Package Manager Version: 5.6
Operating System: MAC OS 10.13.5
Package Version: “contentful-migration”: “^0.10.0”,

runMigration is not intended to be used with the contentful-cli runner. The CLI actually uses runMigration to do the migration. For that it needs to receive a function (what you export from the migration file).

Your “migration file” is a simple one-off method call. Nothing is exported, so nothing can be run. Agreed, the error message could be a bit nicer.

Out of curiosity: where did you get the impression from, that you could do such thing with the contentful-cli and our migration tooling?
