CICD Pipeline error finding package.json

Hi team,

I'm trying to do a CICD pipeline with CDK code for AWS infra,

In my code commit repository, I have a parent folder that contains 2 subdirectories one for my spring boot app and the second for the type script CDK project,

when I created the pipeline with CDK I did cd my-cdk-project

const myrepository = codecommit.Repository.fromRepositoryName(
      this,
      "myrepository",
      "my-repository-name"
    );

const pipeline = new pipelines.CodePipeline(this, "Pipeline", {
      crossAccountKeys: true,
      pipelineName: "cdk-pipeline",
      synth: new pipelines.CodeBuildStep("Synth", {
        buildEnvironment: { privileged: true },
        input: pipelines.CodePipelineSource.codeCommit(
          myrepository,
          "mybranchname"
        ),
        commands: [
          "cd my-cdk-project",
          "npm ci",
          "npm run build",
          "npx cdk synth",
        ],
        primaryOutputDirectory: "my-cdk-project/cdk.out",
      }),
    });

but when the pipeline execute I have the impression that it ignore all commands before the npm ci, so I have this error

I tried to do cd ./my-cdk-project, but still have the same error

I also tried with pipelines.ShellStep... but the error is still the same :

I recommit the package-lock.json but this did not solve the issue

Running command npm ci

did I miss something?

Thank you for your help!
