See [[SC2034]] for an extended discussion of why this is the case. If you know for a fact that the variable is set, you can use `${var:?}` to fail if the variable is unset (or empty), or explicitly initialize/declare it with `var=""` or `declare var`. You can also disable the message with a [[directive]].
