Hey @CarltonHere! I'm here to help you with your DSL file issue. Let's squash those bugs together! 🤖

I found a similar issue related to the problem classifier running all branches instead of only the correct one. In Dify 0.13.2, a known issue occurs when multiple paths from an IF/ELSE statement connect to the same problem classifier, causing it to execute all paths. A temporary workaround is to add an empty component (like assigning a value to an empty variable) in all paths between IF/ELSE branches to prevent this behavior [1].

Additionally, there was a closed issue where the chatbot workflow returned answers containing other branches. This was resolved by fixing the answer node stream processing in conditional branches [2]. You might want to check if a similar fix applies to your version or if a workaround can be implemented based on these insights.

To continue talking to Dosu, mention @dosu.

Thanks, adding an empty component does work, but it can be confirmed that this is a BUG, hoping to be thoroughly resolved.

For me also works to add an empty variable assigner before EVERY ANSWER inside my workflow...
A lot of time wasted to stop everything and manually fix this bug inside all workflows...
