I’ve had an external build trigger.
The URL was https://cloud.docker.com/api/build/v1/source/SOME-UID/trigger/SOME-UID/call/
It now reports 301 Moved Permanently.
Fair enough, since everything moved to hub.docker.com. I don’t see why you didn’t migrate the triggers, but you’ll have your reasons.
Nevertheless, I would now like to set up that build trigger again. But this does not seem possible unfortunately. Every time I enter a name for the trigger on the Build Configurations page and then click the + button, the text is cleared and nothing happens. I’ve tested on Firefox and on Safari. Please fix this.
