Stack creation fails on CICDCustomResource creation

I have run through the build as per the readme instructions. The stack creation gets to the CICDCustomResource step and fails with event description:

Received response status [FAILED] from custom resource. Message returned: See the details in CloudWatch Log Stream: 2022/07/11/[$LATEST]f6f0c3911a0045189d0eb9f2d5768fe7 (RequestId: 6279b397-813e-4472-93bf-ccff21981233)

Cloudwatch logs for the event shows:

}

I can see that the lambda fails on requesting the file smart-product-solution.zip from the s3 bucket. This s3 bucket is correct but the file smart-product-solution.zip does not exist.

        const _repo = process.env.CODECOMMIT_REPO
        const s3Bucket = process.env.CODE_BUCKET;
        const s3Key = process.env.CODE_KEY;
        const codeSource = process.env.CODE_SOURCE;
        const s3params = {
          Bucket: s3Bucket,
          Key: `${s3Key}/${codeSource}`
        };

        Logger.log(
          Logger.levels.ROBUST,
          `${event.LogicalResourceId}:${event.RequestType}` //<< this logs "xincIoT/1.0.0/smart-product-solution.zip"
        );

        const file = fs.createWriteStream('/tmp/smart-product-solution.zip'); 
        let smartProductData = await s3.getObject(s3params).promise();//<<<This line here is where is fails
        file.write(smartProductData.Body, () => {
          file.end();
        });

I have looked through build-s3-dist.sh and can't see anywhere that references smart-product-solution.zip. Is there something missing here?

aws-solutions / smart-product-solution
