# Description Improve error when `str replace <pattern>` detects a problem with <pattern>. # User-Facing Changes New "Incorrect value" error: ``` 〉 'C:\Users\kubouch' | str replace 'C:\Users' 'foo' Error: nu:🐚:incorrect_value (link) × Incorrect value. ╭─[entry #1:1:1] 1 │ 'C:\Users\kubouch' | str replace 'C:\Users' 'foo' · ─────┬──── · ╰── Regex error: Parsing error at position 4: Invalid hex escape ╰──── ``` We could fruitfully replace some of the current uses of `ShellError::UnsupportedInput` with this error. 'Incorrect value' is different from 'wrong type' # Tests + Formatting Don't forget to add tests that cover your changes. * none added / changed. Make sure you've run and fixed any issues with these commands: - [x] `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - [x] `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - [x] `cargo test --workspace` to check that all tests pass # After Submitting If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date.
