I don’t know how to fix this issue:

Symfony\Component\DependencyInjection\Exception\RuntimeException: You have requested a non-existent parameter "kernel.runtime_mode.web".

I think I might have encountered it on other Doctrine bundles. You have to define this parameters somewhere. I also recall talking with @xabbuh about this, and how it might be a Symphony bug. I'm AFK but maybe check the fixtures and migrations bundles

@greg0ire looks like we just have to merge up your changes from #2125 into the 3.1.x branch (see #2141)

Ah yes, it wasn't in another bundle actually!
