how to debug error from stripe API call? need a node.js stacktrace across event emitter? - node.js

Question

I have a node webapp that makes various API calls to Stripe using the stripe npm package. Sometimes I get errors like the one below. Notice that the stacktrace is truncated so that I cannot see which stripe API call causes the error and I also cannot see where in my app this API call is made.
Is there anything I can do to get better error stacktraces?
Error: Missing required param: customer.
at Function.generate (/home/molsson/dv/foobar/node_modules/stripe/lib/Error.js:39:16)
at IncomingMessage.<anonymous> (/home/molsson/dv/foobar/node_modules/stripe/lib/StripeResource.js:175:33)

at endReadableNT (_stream_readable.js:1183:12)
at processTicksAndRejections (internal/process/task_queues.js:80:21)
Note: the error itself is just an example. I have already fixed it. I just want to get better stacktraces or a better method of debugging these types of errors quickly.
I'm pretty sure my node version has async stacks by default:
$ node --version
v12.12.0
$ node -p process.versions.v8
7.7.299.13-node.12
I tried running with NODE_OPTIONS='--trace-warnings --stack-trace-limit=9999' but it didn't help.
Does it exists some kind of "async stacktraces across event emitters" debugging thing?

I found a good answer to this question myself. The stripe library fires and event before making a new API request, so you can print a stacktrace from there:
stripe.on('request', request => {
const currentStack = (new Error()).stack.replace(/^Error/, '')
console.log(`Making Stripe HTTP request to ${request.path}, callsite: ${currentStack}`)
})
I added a STRIPE_API_TRACING option to my app that I can turn on if I experience errors without stacks. With the tracing on I can just scroll a bit up in the log and see what API calls was dispatched just before the error happened.
