VM Exception while processing transaction: invalid opcode

[gregrenard]

I'm testing the following code in a setup with Ganache on MacBook Pro :

from ethairballoons.ethairballoons import ethairBalloons

prov = ethairBalloons('127.0.0.1', '..')

carSchema = prov.createSchema(modelDefinition={
    'name': "Car",
    'contractName': "carsContract",
    'properties': [{
            'name': "model",
            'type': "bytes32",
            'primaryKey': True
    },
        {
            'name': "engine",
            'type': "bytes32",
    },
        {
            'name': "cylinders",
            'type': "uint"
    }
    ]
})

carSchema.deploy()

And I get this error message:

>> ... .venv/lib/python3.8/site-packages/web3/_utils/method_formatters.py", line 561, in raise_solidity_error_on_revert
    raise ContractLogicError(f'execution reverted: {response["error"]["message"]}')
web3.exceptions.ContractLogicError: execution reverted: VM Exception while processing transaction: invalid opcode

Do you have any idea what it's happening, the code was working fine and I just restarted and it's not working anymore.
Thank you for your precious help and support.

Try updating ganache. Most probably it is a ganache issue.

Thank you so much for your answer @petrosDemetrakopoulos.

I updated Ganache with the last version 2.7.1 but still have the same error.

Do you have any additional suggestions for troubleshooting? I'm running out of ideas. It's been nearly two days, and I'm still trying to figure out what's causing the issue. Completely crazy, I did not change anything, just restarted the service both on my Mac and Ubuntu server and I have the same issue

Thank you again for everything you're doing.
