Groovy execute bash script that has ssh - linux

Question

I am trying execute a bash script from my grails app. The script has a ssh call in it. I am using keys to connect between servers.
If I run the script via CLI it works as expected but when I run it via the grails app the script runs but only the part that deals with the local machine. I do not see any output from the remote script.
Any help in pointing me in the right direction will be appreciated.
Bash Script:
echo "Starting Data pushed..."
ssh -t -i /path/to/.ssh/id_rsa_remote_user remote_user#remote_server 'sudo /opt/remote_user/script.sh'
echo "Starting Data pushed... Done!"
Grails/Groovy code:
class CommonService {
def executeScript(String script, Integer waitTimeInMinutes = 1){
def sout = new StringBuilder()
def serr = new StringBuilder()
Integer exitCode = -1
def proc
try {
proc = script.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(waitTimeInMinutes * 60 * 1000)
exitCode = proc.exitValue()
}
catch(e){
log.error e.printStackTrace()
serr << e.toString()
}
log.info "Executed Script: ${sout}"
log.info "Executed Script Extended Output: \n${serr}"
return [output: sout, error: serr, exitCode: exitCode]
}
}
Map outcome = commonService.executeScript('/path/to/local/scripts/pushToProduction.sh', waitTime)
