AWS CodePipeline, build failed & getting error as YAML_FILE_ERROR M

Question

I'm new to AWS CodePipeline and never had past experience with any continuous integration tool like Jenkins, etc. I have created a new AWS CodePipeline as AWS CodeCommit (Code repository) -> CodeBuild (not docker, and environment is NodeJS 7)-> AWS CodeDeploy. Everything is on AWS only. It is an Angular2 project which is running finally deployed on EC2 instances (Windows server 2008). From my local machine, I'm able to commit my code to AWS CodeCommit through active IAM user (Git access) and then I can see CodePipleline starts functioning where Source is fine (green in color) but next step i.e. Build fails (red in color). When I click on its details, I can see following error log :-

Can somebody please guide me on this error? I do not know what does this YAML file means. I googled but nothing relevant found in terms of my NodeJS Angular project.

Thank you, Vinod Kumar

Solution

The YAML file being referenced is the buildspec.yml file required by CodeBuild. More information can be found at http://docs.aws.amazon.com/codebuild/latest/userguide/build-spec-ref.html

Often the user adds the buildspec.yml file but forgets to push it to the repository before executing the CodeBuild. git push your buildspec.yml file and you should be good to go. Also it must be named buildspec.yml not buildspec.yaml as of today.

@EricNord I've pushed buildspec.yml in the root of my project, yet still got this error :( troubleshooting now

@Elaine hope you've found it. If not, I just encountered something similar and apparently Codebuild is very picky about spaces / tabs. I converted all tabs to spaces and removed the spaces on an empty line. Hope this helps

It depends on where you are deploying. IIRC, .yaml is used for lambda and everything else uses .yml.

It took me ages (and I had to edit your answer first) in order to even see that one character had changed in identation. This might be different if you have made any attempt to explain your answer and how it solves the OPs problem.
