The question

Hello everyone, could anyone explain to me the consequences of: VM Exception while processing transaction: invalid opcode.

The context

I'm passing in an integer in web3js that is not mapped to an enum in my solidity contract - I have 2 elements in the enum and I'm intentionally passing in an index of 2, expecting the transaction to fail. The transaction does fail , however I expected a revert and not an invalid opcode. Should I handle parameter sanitisaton in some way?
