During some tests I had timeout in lambda, was running more than 15 minutes and the final logs were missed in datadogs and traces around the whole execution.
I reduced the timeout to 850 seconds and enabled the DD_TRACE_DEBUG = true but I couldn't see anything in logs.
See screenshots of latest logs of lambda execution in datadog and cloudwatch (Highlighted the ones missing in cloudwatch END, REPORT and task timeout):
