test(core): URL-encode bgColor parameter in mermaid.ink API calls (#34466) ## Problem The `draw_mermaid_png()` function fails with HTTP 400 when using named background colors like `white`. This is because named colors get prefixed with `!` (e.g., `!white`) but this special character is not URL-encoded before being added to the API URL. As reported in #34444, the URL parameter `bgColor=!white` causes mermaid.ink to return a 400 Bad Request error. ## Solution URL-encode the `background_color` parameter using `urllib.parse.quote()` before constructing the API URL. This ensures special characters like `!` are properly encoded as `%21`. ## Changes - Added `import urllib.parse` - URL-encode `background_color` value with `urllib.parse.quote(str(background_color), safe="")` - Added 2 unit tests: - `test_mermaid_bgcolor_url_encoding`: Verifies named colors are properly encoded - `test_mermaid_bgcolor_hex_not_encoded`: Verifies hex colors work correctly ## Testing ```bash pytest tests/unit_tests/runnables/test_graph.py::test_mermaid_bgcolor_url_encoding -v pytest tests/unit_tests/runnables/test_graph.py::test_mermaid_bgcolor_hex_not_encoded -v ``` Both tests pass.
