Hi Markus,

thanks for the suggestion!

So, I added capture_message to (1) make sure my connection works (it didn't due to proxy), and (2) to force a flush to Sentry.

Here is a list of changes, which each work independently. I.e. making any one of these changes makes performance info show up on Sentry-Web.

sentry_sdk.init(
     ...
     shutdown_timeout=10,
)

This at end of file:

# sentry_sdk.capture_message(f"Test. Flush some messages..")
# As suggested by @untitaker
# time.sleep(10)
sentry_sdk.flush(timeout=30)
