AWS CDK Code Pipeline Development - Typescript Error TS2307

Problem:

Whilst developing my Code Pipeline, I am experiencing a new error I did not receive with cdk deploy --all in the CLI. All stacks deploy successfully.

Code Build Error Message:

    src/lambda-handlers/queue-consumers/intoMagentoQueueConsumer/index.ts(3,75): error TS2307: Cannot find module '@aws-sdk/client-sfn' or its corresponding type declarations.

Solution

  • Porting the solution from the comments for posterity:

    1. Do you have mismatched npm CLI versions? AWS CodeBuild tsc error TS2307: Cannot find module.
    2. I understand your project has multiple package.json. In your pipeline ShellStep commands, make sure you are running npm ci for each one to install the dependencies.
