POST request firing 2 times

Hi guys,
I conntected a custom form on my page to zapier via a webhook, in order to then write an email with the data in zapier.
Everything is working fine actually, exept that the webhook is triggering the zap 2 times.

I checked it in the console and it also logs 2 times, so the issue must be in the code i guess.
This is the console log:

{"id":"d26bd75b-06ca-4ed9-a274-0bf2d9c5d376","request_id":"6125e2f1-87ef-4f48-889a-ab6a96ef78e0","attempt":"6125e2f1-87ef-4f48-889a-ab6a96ef78e0","status":"success"}
workerLogger.js:103 
{"id":"106526b9-d90f-4a3e-944e-d1bf9e9b3672","request_id":"6125e2f1-7b61-4e52-a828-9f6323a46fc0","attempt":"6125e2f1-7b61-4e52-a828-9f6323a46fc0","status":"success"}
workerLogger.js:103 

This is the code:

//Zapier Hook
      const url = "https://hooks.zapier.com/hooks/catch/10251821/bunylut/";
 
 let datum = $w("#datePicker1").value;
 let beschreibung = $w("#textBox1").value;
 let budget = $w("#dropdown2").value;
 let projekt = $w("#radioGroup1").value;
 let artdesauftrags = $w("#radioGroup2").value;
 let contentverwaltung = $w("#dropdown4").value;
 

  let data2 = {
 "beschreibung": beschreibung,
 "datum": datum,
 "budget": budget,
 "artdesauftrags": artdesauftrags,
 "contentverwaltung": contentverwaltung,
 "projekt": projekt,
 "vorname": $w("#input1").value,
 "nachname": $w("#input2").value,
 "email": $w("#input3").value,
 "agenturname" : itemData.title,
 "agenturemail" : itemData.eMail,
 "agenturvorname" : itemData.vorname,
 "agenturnachname" : itemData.nachname,

        };
 
 var bodyData = JSON.stringify(data2);
 
    fetch(url, {method: 'post', body: bodyData})
    .then ((httpResponse)=>{
      console.log("post succesful");
 if(httpResponse.ok){
 return httpResponse.json();
        }else{
 return Promise.reject("Fetch did not succeed");
        }})
    .then(json=>{
      console.log("Jetzte kommt POST Body");
        console.log(JSON.stringify(json));
        
    })
    .catch(err=>console.log(err));

  })
      //Zapier Hook

Thanks in advance for any help!
Jari
