[WASM Loader] parse_toml failed, using fallback:

Error message

[WASM Loader] parse_toml failed, using fallback:

What it means

Log warning in parseFormula: the WASM parse_toml call (or its JSON result parse) threw, so the formula is parsed with the JavaScript fallback parser instead; the failure reason is logged.

Solutions

1. Check the TOML input and the WASM parse error; the JS fallback parser is used — fix malformed TOML or rebuild the WASM module.
