fix: avoid variable shadowing by renaming local 'errors' variable

The local variable 'errors' was shadowing the standard library 'errors' package,
which can lead to confusion and potential issues when calling package functions.
Renamed the variable to 'errs' to clarify intent and resolve the name collision.
