how the quotes solve the problem for missing argument in the create_and_push_manifest function, when passed "" as seed_prefix

how the quotes solve the problem for missing argument in the create_and_push_manifest function, when passed "" as seed_prefix

That's how function argument parsing works in bash, I guess. Here's a minimum reproducible example:

set -eu

function foo() {
    echo $1
}

var=""
foo "$var"

Try removing the quotes in foo "$var" and see how it fails
