Expected Behavior
I am sorry I am not sure if it's a bug report, something I misunderstood or...
Basically, I noticed that since I migrated my lambda to this library to leverage APM/logs/metrics in Datadog (which is pretty awesome), I am not able to monitor panics anymore. I have the following code:
func main() {
lambda.Start(ddlambda.WrapFunction(handle, nil))
}
and the handle method returns (string, error) as expected. But if the code panics instead of returning an error, then I do not see any trace in APM and I have an INFO log that is not correctly parsed that looks like this:
{"errorMessage":"interface conversion: interface {} is nil, not string","errorType":"TypeAssertionError","stackTrace":[{"path":"github.com/aws/[email protected]/lambda/errors.go","line":39,"label":"lambdaPanicResponse"},{"path":"github.com/aws/[email protected]/lambda/invoke_loop.go","line":122,"label":"callBytesHandlerFunc.func1"},{"path":"runtime/panic.go","line":914,"label":"gopanic"},{"path":"runtime/iface.go","line":263,"label":"panicdottypeE"},{"path":"work/warpstream/warpstream/scripts/lambdas/signups/signups.go","line":114,"label":"CheckRecentSignups"},{"path":"work/warpstream/warpstream/scripts/lambdas/signups/signups.go","line":62,"label":"RunLamdba"},{"path":"common/main.go","line":71,"label":"handle"},{"path":"reflect/value.go","line":596,"label":"Value.call"},{"path":"reflect/value.go","line":380,"label":"Value.Call"},{"path":"github.com/!data!dog/[email protected]/internal/wrapper/wrap_handler.go","line":161,"label":"callHandler"},{"path":"github.com/!data!dog/[email protected]/internal/wrapper/wrap_handler.go","line":61,"label":"WrapHandlerWithListeners.func1"},{"path":"reflect/value.go","line":596,"label":"Value.call"},{"path":"reflect/value.go","line":380,"label":"Value.Call"},{"path":"github.com/aws/[email protected]/lambda/handler.go","line":355,"label":"reflectHandler.func2"},{"path":"github.com/aws/[email protected]/lambda/invoke_loop.go","line":125,"label":"callBytesHandlerFunc"},{"path":"github.com/aws/[email protected]/lambda/invoke_loop.go","line":75,"label":"handleInvoke"},{"path":"github.com/aws/[email protected]/lambda/invoke_loop.go","line":39,"label":"startRuntimeAPILoop"},{"path":"github.com/aws/[email protected]/lambda/entry.go","line":106,"label":"start"},{"path":"github.com/aws/[email protected]/lambda/entry.go","line":69,"label":"StartWithOptions"},{"path":"github.com/aws/[email protected]/lambda/entry.go","line":45,"label":"Start"},{"path":"common/main.go","line":90,"label":"main"},{"path":"runtime/proc.go","line":267,"label":"main"},{"path":"runtime/asm_amd64.s","line":1650,"label":"goexit"}]}
Actual Behavior
I was hoping to get a failing trace in APM and an error log attached to it.
