Host konnte nicht aufgelöst werden – ungültige cURL-Anforderung bei Übergabe mit Variablen

Ich versuche, mit einem Shell-Skript herumzuspielen, und ich glaube, ich habe den Befehl genau so geschrieben, wie er sein sollte, aber ich bekomme seltsame Fehler. Vielleicht bin ich nicht richtig entkommen, aber ich habe alles Mögliche versucht.

myscript.sh

function seconds_to_readable () {
    num=$1
    min=0
    hour=0
    if((num>59));then
            ((sec=num%60))
            ((num=num/60))
            if((num>59));then
                    ((min=num%60))
                    ((num=num/60))
                    if((num>23));then
                            ((hour=num%24))
                    else
                            ((hour=num))
                    fi
            else
                    ((min=num))
            fi
    else
            ((sec=num))
    fi
    echo "$hour""h "$min"m "$sec"s"
}

Und die Ausgabe ist:

Die Anführungszeichen geraten definitiv völlig durcheinander. Setzen Sie Ihr gesamtes JSON-Objekt zunächst mithilfe eines Heredoc in eine Variable und übergeben Sie diese an curl.

Sie können etwa Folgendes tun:

read -r -d '' _json <<EOJSON

    "blocks": [ 
        { 
            "type": "section", 
            "text": {

                "text": ":tada: $ENVIRONMENT website has been deployed in *$(seconds_to_readable $runtime)*" 
                } 
        }, 
        { 
            "type": "context", 
            "elements": [ 
                {

                {
