[!] Unable to create agent script: Script(line 1): SyntaxError: expecting '('

The code seems to be a bit old and there are issues with the javascript engine

also in order to be able to execute that script I added

import { createRequire } from 'module';
const require = createRequire(import.meta.url);

before

// Import the fuzzer base class
const Fuzzer = require("../../harness/fuzzer.js");

I use frida-compile 16.1.4.The compiled agent.js is also the problem. I can't understand why these two sentences are added, and after adding them, my compilation reports an error.
Error: unable to resolve: path, readable-stream, stream, util, readable-stream/passthrough, readable-stream/writable, assert, readable-stream/readable, events, os, buffer, process, constants, tty, net, url, crypto

Oh. Yes it seems that some things in frida-compile have changed. For now you should be able to do the following:

• put the fuzzer script (e.g. test-fuzzer.js) into the harness directory
• run frida-compile -S test-fuzzer.js -o harness.js
• remove the first three lines in the harness.js (frida-compile seems to add some metadata to the file which is invalid JS)
• copy the harness.js to your project dir (e.g. examples/test/)

Then you should be able to run fpicker again. Make sure that you specify the correct compiled JS file (e.g. -f examples/test/harness.js).

This is not an ideal solution. I will have to take a better look at this, but in the short term it should at least get fpicker to run.

Edit: Nevermind, that doesn't work either. I will have to take a closer look...
