Re-deploying as Bitbucket is now enabled on preview environments, see relevant discussion (internal).

Gave this an early look! 👀

@JanKoehnlein What do you think of using the same flow, existing components, and an alert for providing this feedback to the user instead of leading users to this error page?

BEFORE	CURRENT	PROPOSAL

Cc @jldec since you've added the error page proposal #6345. 📝

Cc @laushinka @geropl @jankeromnes @AlexTugarev in case you have any feebdack on this. 🔮

[JanKoehnlein]

@gtsiolis absolutely. This PR is still draft mode because I did a very quick first shot at that and when I tried to look at it the preview env was broken. I can look at that between the meetings today.

I think an entry is missing in

gitpod/components/dashboard/src/projects/NewProject.tsx

Line 435 in 9d54786

setAuthProviders(providers.filter(p => ["github.com", "gitlab.com"].includes(p.host)));

Tested, LGTM:

@AlexTugarev I think this is by design (see screenshot).

Whoops, should be a comment 😬 But IMO fine anyway. Can create a small follow-up PR if needed @AlexTugarev
