What does get_octopusvariable returns in case the variable is set to empty?

Hey Guys, I am trying to validate when a variable is empty with if [ -z “$var” ] ; then in bash, but apparently the variable is set to something else. The variable is set to nothing in the project variables, and if I echo it, it outputs “��e”.

Hi Luis,

If the variable doesn’t have a value we return the result of the following command $(decode_servicemessagevalue "null"). So you could update your script as below

blankValue=$(decode_servicemessagevalue "null")

var=$(get_octopusvariable "SomeVariable")
if [ "$var" == "$blankValue" ]; then
    # if the variable is blank
fi

I hope that helps!

Thank you and warm regards,
Henrik
