Dify version

1.9.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

Create a flow where multiple branches merges into a code node
Make one of the branches a little bit slower
Use the output of the slower branch adfter the code node

✔️ Expected Behavior

execution should wait at the code node, which uses output from all upstream nodes and then continue with the rest of the workflow

❌ Actual Behavior

Upstream nodes that are used in the node, are not waited for.
Execution continues with the rest of the graph considering the output of those nodes as "None" for the code node
The node after the code node errors.
