Serverless-offline: defineService is undefined

Bug Report

Current Behavior
Until 6.5.0, It worked with no issues. Then I upgraded to 6.7.0 then downgraded to 6.6.0 because of the issue below. I had to roll back to 6.5.0 again.

It doesn't crash at the beginning. After a request comes, then it crashes.

Sample Code

offline: Failure: Cannot read property 'defineService' of undefined
TypeError: Cannot read property 'defineService' of undefined

Did you clean node_modules and build it again after downgrade?

Edit:
with rm -rf node_modules. It worked for me.

Nope even with the rm -rf node_modules its failing with the same error. (initial request succeeds, consecutive ones fail)
I do have aws-sdk as a dependency removing that fixes the problem, the issue i am facing might not be the same i do not know.

Can confirm I get it as well on 6.5.0. Haven't noticed the issue before today.

karopolopoulos on 2 Sep 2020

any resolution to this? I am also facing this all of a sudden. @6.5.0

gunnervj on 2 Sep 2020

Resolved the issue by adding

custom:
  serverless-offline:
    useChildProcesses: true

https://github.com/dherault/serverless-offline/issues/931

Upgraded back to 6.7.0

Thank you for your advice. Where did you add this exactly?

Thank you for your advice. Where did you add this exactly?

In serverless.yaml

service: ...
custom:
  serverless-offline:
    useChildProcesses: true

And thanks for that advice, worked great!

Thanks ! This was already driving me nuts.
Can you share a reason for this useChildProcesses:true solving the issue?

From the error It seemed like it was related to aws-sdk not being able to auth...
Just guessing: maybe forking child process inherits previous auth... and without that would create new process with no auth performed against aws?

Solved my issue as well, thanks

rozaydin on 2 Sep 2020

Had a similar issue using pino logger (pino-http/express-pino-logger) where without the useChildProcesses option I get a
TypeError: instance[setLevelSym] is not a function

zoellner on 2 Sep 2020

useChildProcesses resolves the issue for us as well, but also causes request times to be an order of magnitude slower (from <50ms to >500ms), so this isn't a long term solution, I hope.

From aws-sdk, the code in question:

var Service = AWS.Service;
var apiLoader = AWS.apiLoader;

apiLoader.services['sts'] = {};
AWS.STS = Service.defineService('sts', ['2011-06-15']);

Appears that the core AWS module is being compromised at some point.

FYI, earlier closed issue points to using allowCache to avoid error: https://github.com/dherault/serverless-offline/issues/1075#issuecomment-682820809

smundro on 4 Sep 2020

BTW, I think package.json for 6.5.0 is "serverless-offline": "~6.5.0". Actually, "^6.5.0" can install 6.x.

kennyhyun on 21 Sep 2020

Encountered this issue today using, "serverless"-offline: "^.6.7.0".

Both suggested fixes are working but useChildProcesses is slower as mentioned.

custom:
  serverless-offline:
    useChildProcesses: true # ~300ms
    allowCache: true # ~100ms

reilg on 21 Sep 2020

The script from @cchamplin also fix it, no need to use useChildProcesses or allowCache.

Look at theses 2 comments

custom: serverless-offline: useChildProcesses: true
Works for me as well!

JSnaruto on 26 Sep 2020

If you do not want to add useChildProcesses, it has been fixed in 6.8.0

I am also having this issue;

I have a lambda function with an API Gateway that reads from S3.

  "dependencies": {

    handler: ./src/lambdas/surveyHandler.getSurveys

    events:
      - http:
          method: get
          path: /survey
          private: true

My function:

import { APIGatewayProxyHandler } from 'aws-lambda';
import { S3Client } from '../lib/s3Client';
import 'source-map-support/register';

export const getSurveys: APIGatewayProxyHandler = async (_event, _context) => {
  const s3Client = new S3Client();
  const s3Response = await s3Client.get(
    'databucket',
    'surveys.json'
  )

  return {
    statusCode: 200,
    body: JSON.stringify(s3Response, null, 2),
  };
}

The first request works fine, I get back the correct response. The second request fails with;

offline: GET /qat/survey (λ: surveyAPI)
offline: Failure: Cannot read property 'defineService' of undefined
