"Cannot read property 'package' of undefined"

[Thukyd]

Hello,

I want to build an Alexa Skill using typescript and serverless - which are both quite new for me. The basic code - before I added typescript - was running just fine. But with typescript I got an error:

Using powershell and tried to get more infos with the SLS_DEBUG. It showed me an error for the serverless-plugin-typescript

cmd /c "set `"SLS_DEBUG=*`" & serverless invoke local --verbose -f browserkiosk  -p ./testdata/deepSpecificPicture.json "

My additions on typescript in the serverless.yml

plugins:
  - serverless-offline
  - serverless-plugin-typescript

My additions in the package.json

  "dependencies": {
    "ask-sdk": "^2.0.1"
  },
  "devDependencies": {
    "@types/node": "^10.0.2",
    "serverless-offline": "^3.20.3",

  },

Does anybody have a clue how to handle this? Didn't I set it up correctly?

Got the exact same problem, not sure what is going wrong.

For me, this happened when I was in a wrong directory and tried to invoke a function that didn’t exist.

Solved by switching to the right directory and specifying the correct function name.

I got this issue when I try to invoke the wrong function name. Just make sure you put the right name. serverless invoke local -f [FIX_THIS] -p ./testdata/deepSpecificPicture.json
