See https://github.com/ooni/probe-engine/runs/1296480496. Excerpt of the issue:

2020-10-23T06:17:59.6045081Z --- FAIL: TestIntegrationInterruptExampleWithInput (7.39s)

This may depend on the flip between the old and the new infrastructure during Sprint 24.

An easy way to reproduce is running ./miniooni -i http://www.x.org -vvv example_with_input_non_interruptible. This seems something that changed in the refactored backend. I will disable the failing integration test for the time being. Disabling the failing test is quite useful for the time being, because it enables me to merge other fixes with confidence.

Merged into ooni/backend#461

Reopening since it's convenient for me to separate this from ooni/backend#461
