[qperrot]

Describe the bug (observed vs expected behavior)
Error will tring to do :
const declareResponse = await account.declare({ contract: compiledContract, casm: compiledSierraCasm, });
With devnet running in forking mode.

Not reproducible on alpha-goerli

• This issue is only present on Devnet and cannot be reproduced on alpha-goerli (check the box if true).

To Reproduce
Steps to reproduce the behavior:

1. ... starknet-devnet --fork-network alpha-goerli.
2. ...StarknetJs
   const declareResponse = await account.declare({ contract: compiledContract, casm: compiledSierraCasm, });
   ...

Devnet version

This code works if I am not running devnet in fork mode.

• I am using Devnet version: 0.5.1
• This happens with a dockerized Devnet (check the box if true).
• This does not appear on the following Devnet version:

This happens when trying to declare an already declared Cairo1 class in forked mode. The loading here:

starknet-devnet/starknet_devnet/forked_state.py

Line 109 in b738832

compiled_class = CompiledClassBase.load(compiled_class_dict)

should be done using the utility function already defined in

starknet-devnet/starknet_devnet/forked_state.py

Line 51 in b738832

def _load_compiled_class(class_dict: dict) -> CompiledClassBase:

Will create a fix today.
