We've seen it, but sofar no clue why it would fail at this step. We're looking into it.

At the time of writing upload does not have any tests anyway so the build status is irrelevant

[kenjis]

The reason is

[Codeception\Exception\ConfigurationException]
UnitTester class doesn't exists in suite folder.
Run the 'build' command to generate it

Probably Codeception changed. Now it needs tests/_support/UnitTester.php.

According to error message, running below command solves the problem.

$ vendor/bin/codecept build
