Hi there,

I followed the steps [here](https://github.com/onflow/kitty-items/tree/master/kitty-items-deployer) to run “kitty-items/kitty-item-deployer”.

After issuing the command of “npm run start:dev”, there seems to be errors when deploying “kibbles contract”. It seems to be related to invalid address for chain flow-testnet.

Here is the error:

* * *

deploying…  
deploying kibbles contract…  
add contract name: Kibble  
error Error: failed to get account from the execution node: 2 errors occurred:  
\* rpc error: code = InvalidArgument desc = address 0000000000000000 is invalid for chain flow-testnet  
\* rpc error: code = InvalidArgument desc = address 0000000000000000 is invalid for chain flow-testnet

* * *

Any advices?

Thanks so much!

Hi,

Sorry for the late response!

You can fix it by setting the “ports” in “kitty-items/api/docker-compose.yml” correctly. It was caused by the set-up of “postgres” in your machine.

Thanks, and have a good day!
