Cannot determine from-address for a transaction with the API

[som-dev]

Using testnet with v0.2.0.

Calling qrl_pb2.GetBlockByNumberReq() for 12703, in the list of transactions, I cannot determine the from-address for transaction 05f0859e14cd10357661e92d7c3d5a358c04bb0155af0daf47620db6eef65136.

If I call qrl_pb2.GetTransactionReq() for this transaction, I also cannot determine the from-address.

The block explorer does display the from address so I feel like I am doing something wrong?

The odd part is that the to-address is a multisig address. Seems like non-multisig transactions will have a from-address or master-address populated. Not sure if I am using old API or misinterpreting the results.

Here is my output:

The addr_from is not provided by the API, neither the field addr_from exists in the QRL transaction. addr_from is derived from the public_key if master_addr is empty.
If master_addr exists then addr_from is the master_addr and the address derived from the public_key is the address that signed the transaction for master_addr due to Slave relationship.

Thanks for the explanation, I figured I was interpreting something wrong.
