Missing vertex error

Got a few builds setup and running, but one of them is erroring with a message “Missing vertex” search the code on github and could not find that string, guessing its yaml config related anyone able to enlighten me as to what the error is trying to tell me ?

Sorted but for other people reference, this is the issue I had, I renamed one of my services and did not update the depends_on stage to use the new service.

What’s interesting is this does not seem to error when you run drone exec only when it was run on the server, this could be version related not sure.
