I am loading userdata script using AWC CDK typescript code as below.

let userDataScript = fs.readFileSync(path.resolve("./lib/helpers/bootstrap.sh"), "utf8");
  
instance.addUserData(userDataScript);

The script runs only partially and doesn't seem to run below statements as I see : No jq pacakage available message in logs.

echo "Installing epel release"  >>  /tmp/cfn-init.log 

yes | rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm  >>  /tmp/cfn-init.log 

echo "Finished Installing epel release"  >>  /tmp/cfn-init.log 


echo "Installing yum update"  >>  /tmp/cfn-init.log 
yum -y update   >>  /tmp/cfn-init.log 

echo "Finished Installing yum update"  >>  /tmp/cfn-init.log 


echo "Installing  jq"  >>  /tmp/cfn-init.log 
yum -y install jq   >>  /tmp/cfn-init.log

Strange part being, if I run these commands from console using SSM session manager, everything works as expected. Any suggestions please?

Thanks for your help.

Removing carriage return (\r) from the shell script helped to resolve the issue.
