Cannot parse "serverless.ts": Resolution of "ts-node" failed with: "ts-node" not found

[Antonio Lopes]

Hey there,

According to the atlassian/serverless-deploy:1.2.0 (https://bitbucket.org/atlassian/serverless-deploy/src/master/), to set different Serverless configuration file we should define CONFIG param. However, it doesn't say anything about the ts-node.

Anyway, after config it according to the doc:

image: atlassian/default-image:3

pipelines:

  pull-requests:

    master:

      - step:

        name: Deploy to Production

        deployment: Production

        script:

          - pipe: atlassian/serverless-deploy:1.0.0

            variables:

              AWS_ACCESS_KEY_ID: $AWS_ACCESS_KEY_ID

              AWS_SECRET_ACCESS_KEY: $AWS_SECRET_ACCESS_KEY

              AWS_DEFAULT_REGION: 'us-east-1'

              CONFIG: 'serverless.ts'

              EXTRA_ARGS: '--stage production --verbose'

I got the following error.

So, I was wondering if you guys have any idea.

Hello @Antonio Lopes  and thank you for reaching out to Community! 

From the error being shown, it seems like your serverless deploy is looking for the ts-node package, but this does come installed in the pipe's container by default.

In such case, you can install the ts-node package and any other package you need by using the pipe's variable

PRE_EXECUTION_SCRIPT

This should point to a script file that will be run inside the pipe's container at the beginning of its execution.

In the example below, we are creating a script during the run-time to install typescript and ts-node packages, and executing it inside the pipe as a PRE_EXECUTION_SCRIPT : 

script:
  - echo 'npm install typescript ts-node' > .my-script.sh
  - chmod 005 my-script.sh
  - pipe: atlassian/serverless-deploy:1.2.0
    variables:
      AWS_ACCESS_KEY_ID: $AWS_ACCESS_KEY_ID
      AWS_SECRET_ACCESS_KEY: $AWS_SECRET_ACCESS_KEY
      AWS_DEFAULT_REGION: 'us-east-1'
      CONFIG: 'serverless.ts'
      EXTRA_ARGS: '--stage production --verbose'
      PRE_EXECUTION_SCRIPT: '.my-script.sh'

Hope that helps! Let me know in case you have any questions.

Thank you, @Antonio Lopes !
