I'm trying to call a RESTlet from another script, in this case a Suitelet, and in the past I've done this using url.resolveScript. Here's the code I'm using:

var suiteletURL = url.resolveScript({
            scriptId: 'customscript_rl_test',
            deploymentId: 'customdeploy_rl_test',
            returnExternalUrl: false
        });
   
        var response = https.get({url: suiteletURL});

        log.debug({title: "response", details: response});

But this is what I get:

SSS_INVALID_URL
{
   type: "error.SuiteScriptError",
   name: "SSS_INVALID_URL",
   message: "The URL must be a fully qualified HTTPS URL.",
   id: null,
   stack: [
      "createError(N/error)",
      "execute(/SuiteScripts/CSG_SS_Test.js:16)",
      "createError(N/error)"
   ],
   cause: {
      name: "SSS_INVALID_URL",
      message: "The URL must be a fully qualified HTTPS URL."
   },
   notifyOff: false,
   userFacing: true
}

Obviously I can return a FQDN from getURL, but then I'd need to pass authentication info, which is what I'm trying to avoid here. Am I doing something obvious wrong? This looks identical to how I've done it in the past.

Not sure why it would have stopped working, but as of 2020.2, you can call

https.requestRestlet()

rather than

url.resolveScript

followed by

https.get

. Authorization headers are automatically added to your request so you don't have to build them.

You might try https.requestRestlet()

Ahh awesome. I'll try that now. Thanks, guys!

Be aware it's only available server-side

Yep. That's what I want. Thank you!
