Vercel preview deployments are immediately cancelled and restarted

I’ve just enabled Vercel’s automated deployments for previews with github.

I’m seeing this weird behaviour where a deploy is created, and then is immediately cancelled after 1 second

Then, a new deployment is created, which then builds successfully.

In our CI we then get a failure reported in GH, which is annoying but tolerable, as once the new deploy finished it updates, it just marks as failed for 3 mins or so.

However, we also use github’s merge queue feature, and the moment a CI failure is reported, it boots the PR out of the merge queue. This happens once on every PR and completely obviates the benefit of the merge queue.

Is there some kind of config I can change to adjust this behaviour?

We are using the Neon integration
