If you find the answer from one of these, please let us know by solving the thread!

The issue happens because the query in Node.js doesn’t specify the schema (railway.vendedores) and dni may be stored as a string, causing the request to hang or return nothing.

Use the full table path and cast dni as a string in your query:

const query = 'SELECT COUNT(*) as count FROM railway.vendedores WHERE dni = ?';
db.query(query, [String(req.params.dni)], (error, results) => {
  if (error) return res.status(500).json({ error: 'Error al verificar DNI' });
  console.log(results);
  res.json({ available: results[0].count === 0 });
});
