Fulfilling request failiure on a custom Ethereum Aura PoA network

[ngyam]

• Network: Volta (Aura PoA via Parity)
• Ethereum client and version: Parity 2.5.7 (remote RPC)
• Host OS: Ubuntu 16.04
• Commit: 6fe20152b1c0954a55d79d28aa9ed4b4a521b333 , using Docker (smartcontract/chainlink:latest)

Hi, I tried to set up Chainlink on our Ethereum testnet, which seemingly went well until the last step of your FulfillingRequests tutorial. When I try to call requestEthereumPrice of the deployed ATestnetConsumer contract, the transaction succeeds, but:

• the job does not appear in the GUI like it never happened
• there is the following error message in the link node logs:

Am I doing something wrong?

[ngyam]

the problem was that I used the 0.5 version of the contracts. I used the old ones and it was fine.
