this is a fix to #1570 .

The underlying issue in #1570 stems from how []byte("xxx") is handled: it's treated as a constant, yet its value can still be altered. This mutability leads to unintended persistence of its state across loop iterations.

The proposed resolution involves modifying the preprocessing stage to avoid converting an untyped string directly into a []byte type.
