Node.js failed to load resource

Question

I've been working with node.js with sqlite3 database. Below is one of my endpoints to get data from the database.

app.get('/newGame', async (req, res) => {
  try {
    let name = req.query.name;
    let size = req.query.size;

    let db = await getDBConnection();
    let insertGameQry = 'INSERT INTO games (winner_id) VALUES (null);';
    let insertGameResult = await db.run(insertGameQry);
    let gameId = insertGameResult.lastID;
    res.json({'game_id': gameId});
  } catch (err) {
    res.type('text');
    res.status(SERVER_ERROR).send(SERVER_ERROR_MSG);
  }
}

I first get the two query params from the request and connect to the database by getDBConnection() , and then insert a null value to winner_id of the table games (since there's still not a winner), and thus get the gameId in the same table which auto increments by using lastID . However, I constantly get a server 500 error when I clicked the corresponding button at the client side. I've included all the dependencies and confirmed to have the correct project structure and a .db file. Is there any way to get where the problem is? I've also tried to console.log the query parameters in google DevTool and it works fine. However, when I console.log the gameId , it prints nothing on the console. Can anybody provides a method for debugging?

Check your sqlite3 database schema to see if winner_id has NOT NULL set.
