The webpack config is as so, and expects a 
servicePath
 however as you can see it's undefined.
Copy code
{
  servicePath: undefined,
  nodeVersion: 10,
  options: {
    aliases: [],
    stats: false,
    caching: true,
    linting: true,
    fixPackages: [],
    packager: 'npm',
    copyFiles: null,
    concatText: null,
    sourcemaps: true,
    forceInclude: null,
    ignorePackages: [],
    packagerOptions: {},
    tsConfig: 'tsconfig.json',
    forceExclude: [ 'aws-sdk' ],
    externals: [ 'knex', 'sharp' ],
    rawFileExtensions: [ 'pem', 'txt' ]
  }
}
Here's my 
serverless.yml
Copy code
# NOTE: update this with your service name
service: notes-api

# Create an optimized package for our functions 
package:
  individually: true

plugins:
  - serverless-bundle # Package our functions with Webpack
  - serverless-offline
  - serverless-dotenv-plugin # Load .env as environment variables

provider:
  name: aws
  runtime: nodejs10.x
  stage: dev
  region: us-east-1
  # To load environment variables externally
  # rename env.example to .env and uncomment
  # the following line. Also, make sure to not
  # commit your .env.
  #
  #environment:
  #  SAMPLE_ENV_VAR: ${env:SAMPLE_ENV_VAR}

functions:
  hello:
    handler: handler.hello
    events:
      - http:
          path: hello
          method: get
j
@Joshua Harrowell in your 
package.json
, whats the version of 
serverless-bundle
?
j
Using 
3.2.0
- Got slightly further where if I change 
handler.js
to 
exports.hello
then it works. This was after reinstalling the global 
serverless
NPM package however I'm getting ES6 errors if I use the default provided by the tutorial. A colleague who's on the same version of node as myself isn't getting this issue so I'm slightly confused 😅
Copy code
Your Environment Information ---------------------------
     Operating System:          darwin
     Node Version:              12.22.1
     Framework Version:         2.37.0
     Plugin Version:            4.5.3
     SDK Version:               4.2.2
     Components Version:        3.8.3
Basically seems the transpiling isnt working
j
So the only change you made was rename the export?
j
That fixed my initial error, but further into the guide stuff like 
import x from y
also doesnt work
This is without any changes from the guide.
Tried doing fresh pulls from the source repo, installing and reinstalling the global serverless and different node versions
j
Oh something seems seriously broken then. And the older version of serverless-bundle didn’t work
j
Yeah, pretty confusing all round - My colleague has no issues but I've got the same issue on 2 machines. I just started my new role on Monday so I'm on a fresh Macbook, but using NVM so don't see that would cause a massive problem
j
Can you try an older version of Serverless Framework?
j
Sure thing, any version you recommend?
j
Hmm not entirely sure. Maybe something from a couple of weeks ago? Let me know what you find. I’ve to step away for a bit.
j
No worries, thanks for the help so far!
Dropped down to 
2.35.0
and it worked perfectly, thanks a lot!
j
Wow, that's weird that the latest release completely broke it.
