This affects your wiki if you are using both Flow and Nuke.

We recently fixed https://phabricator.wikimedia.org/T162621 , an issue with Flow's Nuke integration.

This has now been merged to master as well as the two supported Flow release branches (1.27 and 1.28):

master - https://gerrit.wikimedia.org/r/#/c/348407/ (merged) 1.27 - https://gerrit.wikimedia.org/r/#/c/348408/1 1.28 - https://gerrit.wikimedia.org/r/#/c/348409/1

This has already been deployed to WMF production.

There is an unrelated Jenkins issue with 1.27 and 1.28. Until those are merged, you can download the patches using Download->Checkout in the top-right of Gerrit. Sorry for the inconvenience.
