Hook manager attach to app complains Cannot read property 'getDefaultBridge'

[cryptax]

In Dexcalibur hook manager panel, I click on attach to app.

Note that frida_server is running despite what the GUI says (see Issue: #32).

generic_x86_64:/ $ ps -u root | grep frida
root         16627 16617   79892  61196 poll_schedule_timeout 0 S frida_server
root         16648     1   14308   4552 poll_schedule_timeout 0 S frida-helper-32

Dexcalibur console says:

The GUI does not say anything special:

The app is running too:

This error also occurred to me because frida client doesn't recognize the emulated device (mine was Nox). To let it works I needed to do some little modifications on the Frida client

Can you say me howdid you solve this error ?

Can you say me howdid you solve this error ?

I solved it by cloning Dexcalibur repository and manually modifying the file "dexcalibur\node_modules\frida\dist\index.js" with a workaround.

It recognize the Nox USB emulated Device without matching it by id but trought type:

I noticed that in my case it tries to match the device USB with id "127.0.0.1:62001" without success even if id was correct (maybe this is due to the fact that the input id needs to be escaped for first, but I'am not sure).

Hope it helps you guys.

@giudon010 Thanks, that sound interesting, it's more an issue related to frida. Did you try with latest frida ?
