Getting UnknownEndpoint error

[SatoshiMD]

I'm getting this error below when trying to mock s3

UnknownEndpoint: Inaccessible host: `mock-bucket.s3.mk-mock-1.amazonaws.com' at port `undefined'. This service may not be available in the `mk-mock-1' region.

Here is my test script

const AWS = require('aws-sdk')
const AWS_MOCK = require('aws-sdk-mock')

describe('Test S3', () => {
  beforeEach(() => {
    process.env.BUCKET = 'mock-bucket'
  })

  it('Test s3 get object', async () => {
    const event = {
      objectKey: 'demo.json'
    }

    AWS_MOCK.mock('S3', 'getObject', function (params, callback) {
      callback('not found', null)

      const body = {
        Body: JSON.stringify({})
      }
      callback(null, body)
    })
  })
})

Also I'm using v5.1.0 aws-sdk-mock

Any idea?

Try to import mock module before importing the original one. Like this

import AWSMock from 'aws-sdk-mock';
import AWS from 'aws-sdk';

// your code ...
