An error occurred (ValidationException) when calling the CreateComponentVersion operation

I am following IoT Greengrass tutorial - https://docs.aws.amazon.com/greengrass/v2/developerguide/defer-component-updates-tutorial.html. I am stuck on the step "gdk component publish". I am unable to publish the helloworld component to cloud service from my development computer.

Issue

=============================== ERROR =============================== Could not publish the component due to the following error. Failed to publish new version of component with the given configuration. Creating private version '1.0.0' of the component 'com.example.BatteryAwareHelloWorld' failed. An error occurred (ValidationException) when calling the CreateComponentVersion operation: Invalid Input: Encountered following errors in Artifacts: {s3://BUCKET_NAME/COMPONENT_NAME/COMPONENT_VERSION/com.example.BatteryAwareHelloWorld.zip = Specified artifact resource cannot be accessed}

Artifact is successfully created in S3 but it is failing to create component on IoT Greengrass service. I have given s3 full access to the user access keys in ~/.aws/credentials. Also given full access on role "GreengrassV2TokenExchangeRole" which Greengrass core devices use to download components from s3.

Can anyone suggest what am I missing here.
