        SAM CLI now collects telemetry to better understand customer needs.

        You can OPT OUT and disable telemetry collection by setting the
        environment variable SAM_CLI_TELEMETRY=0 in your shell.

You are using source maps, note that this comes with a performance hit! Set Sourcemap to false and remove NODE_OPTIONS:
--enable-source-maps to disable source maps.

Configuring SAM deploy
======================

        Looking for config file [samconfig.toml] :  Found
        Reading default arguments  :  Success

        Setting default arguments for 'sam deploy'
        =========================================
        Stack Name [sam-app-example]:
        AWS Region [ap-northeast-1]:
        #Shows you resources changes to be deployed and require a 'Y' to initiate deploy
        Confirm changes before deploy [Y/n]:
        #SAM needs permission to be able to create roles to connect to the resources in your template
        Allow SAM CLI IAM role creation [Y/n]:
        #Preserves the state of previously provisioned resources when an operation fails
        Disable rollback [y/N]:
        HelloWorldFunction has no authentication. Is this okay? [y/N]: y
        Save arguments to configuration file [Y/n]:
        SAM configuration file [samconfig.toml]:
        SAM configuration environment [default]:

        Looking for resources needed for deployment:

        Managed S3 bucket: aws-sam-cli-managed-default-samclisourcebucket-czf78z0qr3am
        A different default S3 bucket can be set in samconfig.toml and auto resolution of buckets turned off by setting resolve_s3=False

        Parameter "stack_name=sam-app-example" in [default.deploy.parameters] is defined as a global parameter
[default.global.parameters].
        This parameter will be only saved under [default.global.parameters] in /home/sondon/dev/aws/apps/sam-app-example/samconfig.toml.

        Saved arguments to config file
        Running 'sam deploy' for future deployments will use the parameters saved above.
        The above parameters can be changed by modifying samconfig.toml
