Scenario Initialization Error – "linked feeder '24' was not found for the aggregator 'undefined'"

Hi Make Community,

I’m encountering an issue with one of my scenarios that prevents it from initializing. Here’s the error message I get:

Scenario initialization failed with an error.

Error:
Cannot initialize the scenario because of the reason ‘Route 2 cannot be initialized because route 2 cannot be initialized because route 2 cannot be initialized because route 2 cannot be initialized because unexpected configuration error: linked feeder ‘24’ was not found for the aggregator ‘undefined’’

Setup:

  • I’m using an iterator module, which is properly connected to the module before it.
  • The error occurs immediately at initialization, and nothing runs.
  • Route 2 seems to be the issue, but I’ve already:
    • Deleted and reconnected the iterator.
    • Removed filters.
    • Tried simplifying the flow – same result.

Questions:

  • Is this a known issue or bug with iterators and branching?
  • Any idea how I can fix or reset this error without rebuilding everything from scratch?

Any help or suggestions are appreciated!

Thanks,
