maybe just a question, the keyfile cannot set to a secure element engine

[jiangpen]

I verified I can do below when to bridge mosquitto
bridge_keyfile pkcs11:model=ATECC608A;manufacturer=Microchip%20Technology%20Inc;serial=xxxxxxx;token=00xx;object=device;type=private
but when I do the same for keyfile, it does not work:
keyfile pkcs11:model=ATECC608A;manufacturer=Microchip%20Technology%20Inc;serial=xxxxxxx;token=00xx;object=device;type=private
show error of:

Unable to load module (null)
Unable to load module (null)
PKCS11_get_private_key returned NULL
1701408790: Error: Unable to load engine private key file "pkcs11:model=ATECC608A;manufacturer=Microchip%20Technology%20Inc;serial=xxxxx;token=00xxx;object=.

1701408790: OpenSSL Error[1]: error:26096080:engine routines:ENGINE_load_private_key:failed loading private key

anyone know the difference? thanks

I'm also getting this error. Is there any solution for this?

Could it be that there is not PKCS11 support for bridge connections?
