[BUG] Contracts calling Chain.create function fail at deployment on local-node

[bogdan-manole]

Describe the bug
When I try to deploy any contract which includes Chain.create calls, deployment fails with Internal server error

To Reproduce
Steps to reproduce the behavior:

1. initiate a new project
2. replace source code from contract/ExampleContract.aes with:

@compiler >= 6

contract Some_Other_Child_Contract = 
    entrypoint sayHi() = 
        "hello"

contract Identity =
    record state = {name: string, surname: string, idNumber: string}

    entrypoint init(name: string, surname: string, idNumber: string) =
        {name = name, surname = surname, idNumber = idNumber }

    entrypoint getIdentity() = state


main contract IdentityServiceCreate =
    type state = list(Identity)
    entrypoint init() = []
    stateful entrypoint createNewIdentity(name: string, surname: string, idNumber: string) =
        let identity = Chain.create(name, surname, idNumber) : Identity
        /*let identity = abort("placeholder Chain.create(name, surname, idNumber)") : Identity*/
        put(identity :: state)
        identity

3. go to test/exampleTest.js and let only the deployment test (57-59) and comment the rest of it (61-88). you should remain with only this one

    it('Should deploy ExampleContract', async () => {
        await contract.deploy([]);
    });

4. execute npm test
5. you will get Internal Error
6. now, in ExampleContract.aes if you comment line 20 and uncomment line 21, like this:

        /*let identity = Chain.create(name, surname, idNumber) : Identity*/
        let identity = abort("placeholder for Chain.create(name, surname, idNumber)") : Identity

7. and run again npm test we will se the deployment succeeds

Expected behavior
The contract should be deployed successfully

@bogdan-manole the v6.0.0 of the compiler is responsible for that error as it cannot handle the code. I didn't remember that problem.

as workaround you can start the compiler using aeproject compiler --v v6.0.2. when using the latest compiler version the contract can be deployed as expected:

marc0olo@DESKTOP-B1QLEDL:~/git/aeternity/test-aeproject$ npm run test

> aeproject-project@1.0.0 test
> mocha ./test/**/*.js --timeout 0 --exit
