I'm seeing the following JavaScript exception when I attempt to navigate to the blue ocean pipeline. Copied from Safari:

 
                                                                [Log] There has been an error while trying to get the run data. (blueocean-core-js.js, line 57459)

AFAICS the issue here is that the 'run' object here does not actually have a 'causes' member:

A similar check would probably be required here:
