Why Won't My AWS CDK Code Build in AWS Code Pipelines?

Problem: In the AWS Code Pipeline Build Stage, I am receiving the error Phase context status code: COMMAND_EXECUTION_ERROR Message: Error while executing command: npm ci. Reason: exit status 254

Desired Outcome: To deploy new changes to the Code Commit Repository, and for the Cloud Formation Stacks to deploy successfully, just like cdk deploy --all.

I have followed this AWS tutorial. Everything deploys successfully.

The Code Pipeline Stack:

export class CodePipelineStack extends Stack {
    private readonly codePipeline: CodePipeline;
    private readonly codeRepository : Repository;

    constructor(scope: Construct, id: string, props: StackProps, context: CDKContext){
        super(scope, id, props);

        this.codeRepository = new Repository(this, "Repo-CDK", { repositoryName: "Repo-CDK", description: "Building A Repo using CDK Methodology" });

        this.codePipeline = new CodePipeline(this, "pipeline", {
            pipelineName: "pipeline",
            selfMutation: true,
            synth: new ShellStep('DeploymentStep', {
              input: CodePipelineSource.codeCommit(this.codeRepository, environment),
              commands: ['npm ci', 'npm run build', 'npx cdk synth'],
            })
          });
    }
}

I also have app.synth(); at the bottom of the function that builds the stacks.

The reason that npm ci does not work is that CodeBuild uses an old version of npm.

Updating npm before running npm ci fixed the issue:

const pipeline = new pipelines.CodePipeline(this, 'Pipeline', {
  synth: new pipelines.ShellStep('Synth', {
    ...
    // Update npm before running commands
    installCommands: ['npm i -g npm@latest'],
    commands: [
      'npm ci',
      'npm run build',
      'npx cdk synth',
    ],
  }),
});
