Hi, When I try to use frida-script.js I get an error:

It doesn't matter which app I use (com.twitter.android, tech.httptoolkit.pinning_demo, etc) the result is always the same.

Android 11, Samsung SM G998B (s21 Ultra) rooted. Frida is installed on Windows 11 / Python3.7

Any idea how to fix this? Thank you.

I've used apk-mitm instead of Frida to disable certificate pinning.

Thanks for reporting this @x011. I've heard about similar issues before (#3) - in that case this was a general Frida problem, rather than something to do with the script being used.

If you have a minute, it would be useful if you could confirm that (just check that running other Frida scripts from https://codeshare.frida.re/ fails too, so it's not related to this script).

Either way I'm not sure what causes the underlying issue. Any clues would be very welcome, I'd love to be able to give some advice to get Frida working for the next person who runs into this!
