hello, thanks for awesome guide. but I'm having an error when trying to build now. First it gives the following error when I run the code below protostar deploy ./build/main.json --network alpha-goerli:

[ERROR] Unknown StarkNet network The following StarkNet network names are supported:

• testnet
• mainnet

and if I try to run it like that protostar deploy ./build/main.json --network testnet it outputs the following:

21:42:21 [WARNING] protostar deploy will be removed in the future release
docs starknet.io/documentation/develop/Blocks/transactions/#deploy_transaction Unexpected Protostar error. Report it here: github com/software-mansion/protostar/issues

Maybe you know how this error can be fixed. Thanks
