Sentry not logging chain exception `raise Exception() from e`

Sentry not logging chain exception raise Exception() from e

for example

class FooFail(Exception):
	pass

try:
	1/0
except Exception as e:
	raise FooFail('a foo exception.') from e

Since e contain the information use to identify cause of root exception. It is very important to see chain exception detail. The missing of detail in Sentry issue panel.

If you see a plaintext traceback you will have a bad time for a lot of reasons:

1. those events do not group well into issues as we don’t have semantic knowledge of the stacktrace (it’s just a string to the server)
2. apparently, and this is new to me, chained exceptions can also go missing

Usually this is caused by code that stringifies the exception using the traceback module and then logs it. You can find out which logger that is using the logger event tag.

Both exceptions should show on the details page.
