Fix TomlCredentialError

✅ Solution

TomlCredentialError in uv usually arises from missing or malformed `pypirc` or `uv.toml` files that specify credentials for accessing package indexes. To fix, ensure these files exist in the correct location (e.g., `$HOME/.pypirc` or project root) and contain valid TOML syntax with properly configured credentials (username, password or token) for the relevant index URLs. Specifically, check for typos in section names like `[tool.uv]` or `[pypi]` and that the URL matches the expected pattern for your index.
