I am facing "UnimplementedFeatureError: Nested dynamic arrays not implemented here. " when I try to emit an event contains bytes  data;
I have a fix size of data which is 65bytes but there is no supported type to put it in. so I use a dynamic bytes.
I have this event:
event SkillValidated( address indexed user, address  validators, bytes  signatures, //a signature is a 65 bytes );
when I emit the event I got the mentionned error. and when I change it to:
event SkillValidated( address indexed user, address  validators, bytes32  signatures, // I lost part of signature );
How can I resolve the problem, have I to implement a specific type using struct?
