Ink! CalleeTrapped issue demo

I've stuck in getting CalleeTrapped error and created this repo for the issue reproduction.

Please, help to solve it if you have an idea how.

Contracts

• Flipper contract is taken from Ink! examples
  it's flip() message is given 0xC0DECAFE selector
• Caller contract invokes Fipper.flip() message

Steps to Reproduce

1. Build Flipper

cd flipper
cargo +nightly contract build

2. Build Caller

cd ../caller
cargo +nightly contract build

3. Start node

 substrate-contracts-node --dev --tmp -lerror,runtime::contracts=debug 

4. Open CanvasUI, upload and instantiate:
   • Flipper contract
   • Caller contract with callee_contract_address = <Flipper AccountId>
5. Try to execute Caller.call_flipper() as RPC call
   Result: CalleeTrapped
6. Try to execute Caller.call_flipper() as transaction
   Result: ContractTrapped
