API Background Thread

Hello,

I am using CRS980MI to add textblock . Based on requirement I have loop this API. Has anybody use the async function to make sure that API will come back with result and then only it proceed further. I have added return await promise but it doesn't work.

Thanks in advance.

var request = new MIRequest();

        request.program = "CRS980MI";
        request.transaction = "AddTxtBlockLine";
        request.record = {
            CONO: company
            DIVI: "",
            TXID: txid,
            TXVR: "",
            LNCD: "GB",
            TX40: "",
            LINO: xlino,
            TX60: tx60,
            TFIL: "MSYTXH00",
            FILE: "MPLINE00"
        };
        request.includeMetadata = true;
        request.typedOutput = false;
       // request.outputFields = ["LINO"];
         console.log(request);
        var promise = MIService.Current.executeRequest(request);

return await promise;

You are not sharing the entire code. Is this in a function with the async keyword? My guess is that you are not using the await/async correctly.

 
let value = await promise;<code class="token comment">// works only inside async functions

Jay,
you have to handle this in a nested fashion, and add the code to 'present if result valid' in the 'Worker Complete' function instead, thus you can control this just fine.
It's a common mistake to think that you can put the 'check logic' in the function which calls the API Function, since that one will execute 'in parallel', and thus the check will be made before the API call has finihed processing!
Hopefully this helps.

that code is not correct - don't use it.
