AWS CDK Code Pipeline Development - Typescript Error TS2307 - aws-cdk

Question

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.
Lambda Function Import Statements:
import { SFNClient, SendTaskSuccessCommand, SendTaskFailureCommand } from "#aws-sdk/client-sfn";

Porting the solution from the comments for posterity:
Do you have mismatched npm CLI versions? AWS CodeBuild tsc error TS2307: Cannot find module.
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.
