gRPC Before Invoke doesn't work like REST Pre-request script

Help
1

Hi,

for some reason, I am able to run a Pre-request script and set up a Collection Variable (for setting up a token) for REST requests, but when I have the same script run as a Before Invoke script in a gRPC request it fails with the error message:

code: “ECONNRESET”
name: “Error”
message: “socket hang up”
stack: “Error: socket hang up
at connResetException (node:internal/errors:691:14)
at TLSSocket.socketOnEnd (node:_http_client:471:23)
at TLSSocket.emit (node:events:402:35)
at TLSSocket.emit (node:domain:475:12)
at endReadableNT (node:internal/streams/readable:1343:12)
at processTicksAndRejections (node:internal/process/task_queues:83:21)”

Do you have any idea why? what am I doing wrong?

Thank you,

Bar.

@shabib can you share the script that we can use to reproduce this issue locally?

@udit.vasu - there you go

const options = {
url: “https://[[SOME_URL]]/token”,
method: ‘POST’,
header: { ‘content-type’: ‘application/json’ },
body: {
mode: ‘raw’,
raw: JSON.stringify([[BODY_PAYLOAD]])
}
};

pm.sendRequest(options, function (err, response) {
if (err) {
console.error(err);
return;
}

const data = response.json();
console.info(data);
pm.collectionVariables.set("jwt", data.token);

});

The following code snippet works fine for me.

const options = {
    url: "https://postman-echo.com/post",
    method: "POST",
    header: { "content-type": "application/json" },
    body: {
        mode: "raw",
        raw: JSON.stringify({ token: "foobar" })
    }
};

pm.sendRequest(options, function (err, response) {
    if (err) {
        console.error(err);
        return;
    }

    const data = response.json();

    console.info(data);

    pm.collectionVariables.set("jwt", data.token);

});

I wonder if it might be because there is a bug in picking up the local certificate I set in the Certificate Setting for the URL I use. can you help me check for that?
