Butterfly: snappyhexmesh runtime error

The snappyhexmesh component doesn’t work well, and it says

     runtime error(value error exception): need more than 1 values to unpack

And, maybe because of the snappyhexmesh error, some component running after it can’t find folders.
Here are some screenshots and my gh file. Can you help me please?


And there is also something wrong with the solution component. The solution only run 24times, and the u results are far too large, which is xxxe+xx. I really can’t fix it myself. Can you help me?
