Hey everyone. I encountered a dimension mismatch error in the ‘propagate’ function, but it only occurs when it’s called from the ‘model’ function. The ‘propagate’ function passes all tests when I test it with its test cases. Does anyone know where the problem might be?

Please don’t post your code on the forum. That’s not allowed by the Code of Conduct.
I suspect that somewhere in the chain of function calls, you are either using an incorrect variable name, or are using a global variable where you shouldn’t, or you have reshaped some variable that should have been left alone.
As Tom says, the bug is not in propagate. It is in your model logic. You can actually see it in the exception trace you posted: you are passing the wrong argument to the “initialize” routine, so your w value is the wrong shape. It ends up with 7 elements, but it should have 4 in that particular test case.
Once you fix that, your next failure will be that you are not passing all the parameters you need when you call optimize from model.
