Issue Summary

When a user whose email is not registered as a Bitbucket Cloud user (or who has no workspace access) tries to access any Bitbucket workspace, they see a “Resource not found” error and a dashboard link to https://bitbucket.org/. which is expected behaviour

On https://bitbucket.org/, they see “Join a workspace to collaborate with your teammates” and also can click Sign up or Log in under accounts. However, clicking either option keeps refreshing the page and returns them to the same screen, creating an infinite loop.

Steps to Reproduce

1. Step 1 Log in to id.atlassian.com with an email that has not previously logged into Atlassian Cloud / Bitbucket Cloud.
2. Step 2 Try to access a workspace URL you don’t have access to (e.g., https://bitbucket.org/<workspace_id>/workspace/overview).

Expected Results

• User sees “Resource not found” (expected).
• Clicking Dashboard should land on a page where Sign up / Log in takes the user to the Bitbucket Cloud account/workspace creation flow.
• A clear banner/message should indicate the email is not registered for Bitbucket Cloud yet and prompt the user to create an account (and optionally mention they can still join an existing workspace).

Actual Results

Clicking Dashboard lands on https://bitbucket.org/account/workspaces, and Sign up / Log in under accounts results in a never-ending refresh loop because the user does not yet have a Bitbucket Cloud account/workspace.

Workaround

Do not click Sign up or Log in. Click Create workspace instead, which correctly takes the user to the Bitbucket account/workspace sign-up flow.
