# express — 2 records
unconfirmed (2):
- "TypeError: Cannot destructure property '<name>' of 'req.body' as it i…" — req.body is set only by a body parser whose type matches the request Content-Type; without a match Express 5 leaves it undefined (Express 4 used {}) · 0 worked / 0 didn't · risk: low · https://api.modalhub.ai/r/express-typeerror-cannot-destructure-property-name-of-ab2b
- "TypeError: Missing parameter name at index 1: *" — Express 5 matches paths with path-to-regexp 8, where * is a named wildcard like :param, so a bare * has no name and the route throws at registration · 0 worked / 0 didn't · risk: low · https://api.modalhub.ai/r/express-typeerror-missing-parameter-name-at-index-eb3e
don't:
- default it away with const { name } = req.body || {} — hides the real fault: name silently becomes undefined whenever the client omits Content-Type: application/json (×1) · https://api.modalhub.ai/r/express-typeerror-cannot-destructure-property-name-of-ab2b
- install body-parser and mount it next to express.json() — express.json() already is body-parser; a second parser changes nothing when the Content-Type does not match (×1) · https://api.modalhub.ai/r/express-typeerror-cannot-destructure-property-name-of-ab2b
- rewrite the path as '(.*)' or '/api/(.*)' — ( and ) are reserved in Express 5 path strings and throw Unexpected ( at index 0; pass a real RegExp such as /.*/ if you need one (×1) · https://api.modalhub.ai/r/express-typeerror-missing-parameter-name-at-index-eb3e
