How do you use transactions with a Pool?

[jenders-polar]

Below is a snippet of code I am trying to get working... basically I get the pool and call connect on it to get a single connection.

I call beginTransaction on the connection, run my statements, then call commit or rollback.

The problem with this, is that after 3 calls to this function, the pool stops working and doesn't respond to anything.

Am I doing something wrong here? Should I not be using a pool to do transactions?

export async function executeStatements(statements: Statement[]) {
  const pool = await getPool();

  const connection = await pool.connect();
  await connection.beginTransaction();

  try {
    const results = statements.map((statement) =>
      connection.query(
        statement.sql,
        statement.parameters as Array<number | string>,
      ),
    );
    (await Promise.allSettled(results)).forEach((promise) => {
      if (promise.status === "rejected") {
        throw Error();
      }
    });
    await connection.commit();
  } catch (error) {
    await connection.rollback();
  }

  return;
}
