C5 W1 A1 RNN_Step_by_Step; rnn_forward

I’ve looked through the previous queries on this topic, but I don’t seem to have my function correct (exercise 1 was successful):
The output is:

xt was passed as X[:,:,t] and a_prev as a_next to the function rnn_cell_forward …

Can you please give me a hint as to what could possibly be wrong in my function? I can gladly send the entire function separately …
Thank you!!

I found my mistake: error was the initialization of a_next with a0 (and not with a[:,:,0]

Congratulations on finding the solution under your own power. Onward! :nerd_face:
