Image Build Attempt via CodeBuild Failed due to Missing Signature Key?

[jokwuoma]

Hello everyone! I'm currently running through Module 2 of the AWS Modern Application Workshop, and having the Dockerfile, buildspec.yml, code-build-project.json, code-pipeline.json files updated and the container image built and pushed to the Amazon ECR repository within my local environment, things went smoothly at first, so I presumed this would be the case upon having AWS CodeBuild building the image successfully. However, upon running the CI/CD pipeline via AWS CodePipeline, I encountered a failure with the Codebuild task, wherein it provided a log showing the following:

Note: the error shows up at line 155!

I have a suspicion that either the docker or aws version might be contributing to why the "missing signature key" error is showing up in the CodeBuild attempt, but thus far, I cannot say with 100% certainty whether that is the case? Has anyone encountered this issue before, and if not, know of an approach or method that could be helpful in addressing the error, so that it can successfully build and push the image?
