An empty response to the uavcan.protocol.file.Read will have a size of 2 bytes (this is the size of the error field), while the DroneCAN -> Cyphal converter expects at least 4, because it mistakenly assumes that the minimum response size will be like in Cyphal, where there is no tail array optimization.
