Rapdu 6300 error when reading PACE-enabled Greek passport

[Parzivalxx]

Hi, I am getting the following error when reading PACE-enabled Greek passport:

PACE <ECDH> key establishment failed: PACE <ECDH> (4); Failed: ICC Error: General authentication template (step 4) failed sw=6300

I have narrowed it down to this function:

dmrtd/lib/src/proto/iso7816/icc.dart

Line 118 in 8ced760

Future<Uint8List> generalAuthenticatePACEstep4({ required Uint8List data, int ne = 256, int cla = ISO7816_CLA.NO_SM }) async {

it seems the rapdu status is 6300 when it needs to be 9000 when reading in PACE mode.

This error only happens for the Greek passport. It succeeds when reading PACE-enabled Singapore passport.
I have checked the input fields such as the mrtdNumber, date of birth and date of expiry and they are correct.

Are there any additional error/warning entries in the log? Which algorithm is used to establish PACE session?
