C5 W1 A1: AssertionError: Problem 1 in yt_pred expression. Related to by?

I’m getting this error in rnn_cell_forward() function
I checked this thread too

In your rnn_cell_forward() function, did you modify the ‘by’ variable, or modify the ‘parameters’ variable?

Also, that test in rnn_cell_forward_test() specifically checks if your code for computing yt_pred is correct for a specific set of Wya values. So look at your code for yt_pred closely. It doesn’t pass this specific test.
