LOG: [YAML] Init local var not set by some branches (#123137)

It will not be set if:

1. `(TypeStr.starts_with("SHT_") || isInteger(TypeStr)) == false`: here
we want go to switch default.
2. `IO.mapRequired("Type", Type);` fail parsing. It sets error
internally, so probably not important what happen next, so it's go to
the switch
