64 bit emulator returns: unable to handle 64-bit processes due to build configuration

Any idea how I can use the 64 bit version of frida (server/gadget) on an unrooted emulator? I've seen other issues about this but never with a solution.

Instructions:

export PATH="/Users/xxx/Library/Android/sdk/build-tools/28.0.3:$PATH"
python apk_builder.py --apk ~/Desktop/app.apk
python appmon.py -p android -a app -s scripts/Android
[ERROR] unable to handle 64-bit processes due to build configuration
Traceback (most recent call last):

    return Session(self._impl.attach(self._pid_of(target)))

Was running bad version of frida-server.
