Solution

  • You are accidentally trying to have the same agent in 2 flowchart blocks at the same time. This is not allowed.

    How to fix this? Hard to say for your specific case.

    You need to start building models in a way that you catch these problems directly, i.e.:

    1. build extremely simple flow
    2. test test test
    3. add a TINY feature
    4. test test test
    5. rinse and repeat

    this way, you would know instantly which tiny change caused your error and could rectify immediately.

    Now, you are stuck with a huge flow chart and you will have to peel back and simplify until it works. Then, you find your root cause.
