Headless Chrome Python 3.8 on AWS Lambda - unexpectedly exited. Status code was: 127
The error might come from the fact that the chromedriver version and the headless chromium binary you are using aren't the same so make sure to download the same version for both
another reson could be that you are not using linux chromedriver and headless chromium and since lambda work on linux the code won't work
hopefully this was useful.
