We’ll keep an eye out for more reports and continue attempting to reproduce the issue on our end. These linter issues were present in versions 3.4x–3.5x and were largely resolved in v3.75 (except for cases like Buffer on Workflows). If we're seeing them again, there may have been a regression. Please let us know if it's happening in more places.
@Alvin_Wang, in your case, are you seeing these warnings consistently?
