Summary0005566: test_exchange_api_twisted fails
DescriptionERROR Unexpected response code 200/0 to command refresh-reveal-409-conflict in testing_api_cmd_refresh.c:324. So basically it expects a failure, but the code is happy. I suspect (did not check!) the test asks twister for a bitflip and expects a failure, but the bitflip either doesn't happen or happens in a 'harmless' place. In that case, probably specifying more precisely where to flip the bit might help.
Steps To ReproduceWas from 'make check'

I've checked, the test _sometimes_ passes and _sometimes_ fails (random), about 50/50 for me so far.

I've run 5 times this test and it passes always. Please try to update the Twister, if you didn't yet.

I did 'make install' on the latest twister, now it still fails. I got a failure like the above, and a new one:

I got the first error by running the test under Valgrind, but like once out of 20 runs.

Attaching logs from a failing session, again not easily reproducible.
