When working inside actions and mutations, it is important to pass the state to functions.

The first argument should be the state for actions and mutations, while the second argument should be the payload. Here's an example of how your code should be structured:

updateState({ state }, payload)

By following this pattern, you can directly access the state without needing to use 'this.state' in your code.
