How to recover connection pool from "unknown database" error with node mysql2

Question

I'm using the changeUser method in the mysql2 npm package to connect our API to different databases in our database instance:

const pool = createPool({
  namedPlaceholders: true,
  ...dbConfig,
});

async function getConnection(database) {
  const connection = await poolMain.getConnection();
  await connection.changeUser({ database });
  return connection;
}

When I pass an invalid database the connection fails as intended.

But after one failed attempt all following attempts of getConnection fail as well, even when a valid database is passed.

The only solution that I found was to recreate the pool in case of err.code === "ER_BAD_DB_ERROR":

let pool = createPool({
  namedPlaceholders: true,
  ...dbConfig,
});

async function getConnection(database) {
  try {
    if (database === "betenergie_db") {
      return await poolBet.getConnection();
    } else {
      const connection = await pool.getConnection();
      connection.changeUser({ database });
      return connection;
    }
  } catch (err) {
    if (err.code === "ER_BAD_DB_ERROR") {
      pool = createPool({
        namedPlaceholders: true,
        ...dbConfig,
      })
    }
    throw err;
  }
}

Is a more elegant way of recovering the pool without reinstantiating it?
