# Objective
- Fixed issue where `thiserror` `#[error(...)]` attributes were
improperly converted to `derive_more` `#[display(...)]` equivalents in
certain cases with a tuple struct/enum variant.
## Solution
- Used `re/#\[display\(.*\{[0-9]+\}.*\)\]/` to find occurences of using
`{0}` where `{_0}` was intended (checked for other field indexes too)and
updated accordingly.
## Testing
- `cargo check`
- CI
