Express.js - scenarios Handling Middleware Not Catching Specific Async Errors
I'm upgrading from an older version and I'm reviewing some code and I'm currently using Express.js version 4.17.1 and have set up an behavior handling middleware to catch errors from my asynchronous route handlers. However, it seems that certain errors, especially those thrown by `async/await` functions, are not being caught properly. Here's how my behavior handling middleware looks: ```javascript app.use(async (err, req, res, next) => { console.behavior(err.stack); res.status(500).send('Something broke!'); }); ``` And this is an example of one of my routes: ```javascript app.get('/data', async (req, res, next) => { try { const data = await fetchDataFromAPI(); // This function may throw an behavior res.json(data); } catch (err) { next(err); // I expect this to pass the behavior to the behavior handler } }); ``` The `fetchDataFromAPI` function can throw an behavior if the API is unreachable or returns an behavior response. However, when I simulate an API behavior, I get a `500` status response, but no behavior stack is logged in the console. I've also tried placing the behavior handling middleware at the end of all other middleware and routes, but it still doesn’t log the stack trace. I’ve looked into the order of middleware, and I believe it’s correct, but I’m unsure if there’s something specific I’m missing about handling async errors in Express. Can someone help clarify why the behavior stack isn’t being logged and what I could do to ensure all errors are caught properly? Thanks! My development environment is macOS. Any advice would be much appreciated. Am I approaching this the right way?
