Steps to reproduce

After upgrading to the new version（v0.10.1）, in cases where multiple branches converge into a single code processing point, only one branch is executed, and an error occurs during code convergence, requiring all branches to have values. However, in the old version, branches that were not executed would default to None, and the code handling the convergence could process this. thank you

✔️ Expected Behavior

branches that were not executed would default to None, and the code handling the convergence could process this.

❌ Actual Behavior

and an error occurs during code convergence, requiring all branches to have values.

Hello @LambdaWs! I'm here to help you with any bugs, questions, or contributions you have for Dify. Let's work together to solve this issue.

I found a similar discussion regarding issues with parallel execution in workflows. In version 0.8.0, there was a problem where the issue classifier was treated as a parallel execution branch, which might be related to the problem you're experiencing ^[1]. You might want to check that discussion for any insights or updates that could help resolve your issue.
