Trying to send http request from azure function to logic app. Function in Javascript runs without error but the logic app has never been triggered. Here is how i am fetching the endpoint. 

 const fetch = require("node-fetch");

    fetch("https://prod-30.eastus2.logic.azure.com:443/workflows/123axc/triggers/manual/paths/invoke?api-version=2016-10-01&sp=%2Ftriggers%2Fmanual%2Frun&sv=1.0&sig=abc123-XKP-fPs",{method: "POST", body: {"html": html}, headers: {
        "Content-Type": "application/json",
      }})

Can someone explain what is wrong or missing here?

Hi @braxx

I believe html is the object that you have defined in your function and I see that you have not used JSON.stringify to convert it to json object.

fetch("https://prod-30.eastus2.logic.azure.com:443/workflows/123axc/triggers/manual/paths/invoke?api-version=2016-10-01&sp=%2Ftriggers%2Fmanual%2Frun&sv=1.0&sig=abc123-XKP-fPs",{method: "POST", body: {"html": html}, headers: {
"Content-Type": "application/json",
}})

I have tested the scenario at my end and it is working as expected. I will also suggest you to verify whether you have selected "POST" method in the drop down of "When a HTTP request is received" trigger which would cause this issue. 

    let data = {  
        userId: 123,  
        title: "loren impsum doloris",  
        completed: false  
    };  
      
    fetch("https://prod-29.westus.logic.azure.com:443/workflows/yourworkflow/triggers/manual/paths/invoke?api-version=2016-10-01&sp=%2Ftriggers%2Fmanual%2Frun&sv=1.0&sig=_tPma_SSYXNpIe9Eh96Zb_7uoDw0fyfoDofxyJrCBqw", {  
        method: "POST",   
        body: JSON.stringify(data),   
        headers: { "Content-Type": "application/json"}  
      })

You can refer to node-fetch document for more details. You will only see the error/exception if the fetch statement throws the exception. If I pass the wrong syntax in fetch statement then it throws the exception but if I do not convert the object to json then it doesn't throw any exception as you have observed.
