COMMAND_EXECUTION_ERROR AWS CodeBuild

Question

I am trying to setup a s3 bucket and github account to create a pipeline in aws codepipeline service. I am getting an error I can't seem to find. It seems to be related to the NPM Install command, but not sure why. Can someone help please?

COMMAND_EXECUTION_ERROR: Error while executing command: npm i. Reason: exit status 1
