Trying to populate a Jenkins parameter with a list of choices but the parameter stays empty, what could be the reason?

I'm using Jenkins "Extensible Choice" plugin in order to populate a parameter with a list of AWS RDS DB instance names.

In "Choice provider" I chose "System groovy choice parameter".

This is the groovy code which is supposed to return the list of DB's:

//Create buffer to capture command's Standard Out
def sout = new StringBuffer(), serr = new StringBuffer()

//Define here the shell command you would like to execute
def proc = 'aws rds describe-db-instances | grep DBInstanceIdentifier | grep -v Read | awk "{print \$2}" | sed "s/\"//g"'.execute()

//Capture command output into buffer
proc.consumeProcessOutput(sout, serr)

//Time to wait for command to complete
proc.waitForOrKill(1000)

//Converts command output to a list of choices, split by whitespace
return sout.tokenize()

If I run the command in a shell, I get the output properly:

[[email protected] ~]$ aws rds describe-db-instances | grep DBInstanceIdentifier | grep -v Read | awk "{print \$2}" | sed "s/\"//g"
company
company-dev-70-mysql
dev-rds-2017-10-02
company-check-woocommerce
prod

But when I run the job, the drop down menu stays empty.

Any idea what I'm doing wrong?

The second is StringBuilder not Buffer.

def sout = new StringBuffer(), serr = new StringBuilder()
