Issues when using pm.sendrequest in Native GIT

Hello everyone.

I’m trying to migrate some Postman Collection to Postman v12 for my team but I have an issue when I execute pm.sendRequest from Before Request script in Collection.

I did a small tests using a Test Collection and the Request works as expected when using Postman Cloud however the same Request fails when running from Native GIT in Postman.

Can someone please confirm if this is expected or maybe a known issue?

I’m using Postman v12.1.4

Thank you.

Example Collection

Postman collection including a GET request to https://api.restful-api.dev/objects

Before Request Script

pm.test("Status code is 200", function () {
    pm.sendRequest('https://postman-echo.com/get', function (err, res) {
        pm.expect(err).to.not.be.ok;
        pm.expect(res).to.have.property('code', 200);
        pm.expect(res).to.have.property('status', 'OK');
    });
});

Results in Postman Cloud

Works with no issues.

Hey @maintenance-technol7! Thanks for the report. I can notice some inconsistencies in the mentioned workflow. We’ll look into this and provide an update here once the fix is out.

It looks like the same issue I’m experiencing. Posted in Discord:

I tried using the Git-backed workspace. In the pre-request script I’m using pm.sendRequest to send a request to an unrelated API. The engine is not calling the additional API, but instead is triggering the pre-request script again - resulting in an infinite loop (I have console.log in my script) and Postman getting stuck.

Adding this in the pre-request script fixes the issue:

if (pm.request.url.toString() == externalAPI) {
    console.log("Login request — skipping pre-request auth:", pm.request.url.toString());
    return;

This behavior is different for a regular workspace, not Git-backed. Same exact script. Works without the additional condition.

Thanks @guyarad for the workaround! I was experiencing the exact same issue — pm.sendRequest in a collection-level pre-request script was causing an infinite loop and crashing Postman in my Git-backed workspace. Adding the URL guard to short-circuit the pre-request script when the request matches the external API resolved it.

Hopefully the Postman team addresses this soon so pm.sendRequest behaves consistently between Git-backed and regular workspaces without needing a workaround.

Updated Before Request:

const externalAPI = 'https://postman-echo.com/get';

if (pm.request.url.toString() == externalAPI) {
    console.log("External request — skipping pre-request auth:", pm.request.url.toString());
    return;
}

pm.test("Status code is 200", function () {
    pm.sendRequest(externalAPI, function (err, res) {
        pm.expect(err).to.not.be.ok;
        pm.expect(res).to.have.property('code', 200);
        pm.expect(res).to.have.property('status', 'OK');
    });
});
