Invalid parameter, duplicated address: Any ideas?????

[cmilian]

Error trying to send payments with RPC sendmany {"code":-8,"message":"Invalid parameter, duplicated address: PDDfRL3B1fTPqnnWqajdYTSPFwWuTujF28"}

This is breaking my payment, this is NOMP and there someone that is using same wallet for two miners.

Any ideas how I can fix this?

Thanks in advance!

Any ideas how I can fix this?

Combine the two amounts into a single payment?

Require your users to supply a new address for every transaction?

Combine the amounts. The interface is a dictionary. Your input is not well formed if there is duplication.

We had this in our NOMP pool recently, I wrote up the solution that we used here: http://bitcoin.stackexchange.com/questions/34057/error-trying-to-send-payments-with-rpc-sendmany
