What happens if you run the same command as in the tutorial?
BTW, I would spend too much effort on this. Eventually everything will work exactly the same.
Thank you very much for your responsiveness.
The truth is that I don't put a question in the forum except after the attempts
and inability to solve
Because of my little programming experience
About this matter I tried hours before I put the problems in the forum
Second I applied what you referred to in the link
But I have a corrupted zip file
Because the data and parameters required to create it are incomplete
See picture 1
For the old parameters required and that are in the explanation, which are only two parameters
And see picture 2
For the required new parameters, which are 5 parameters
When I upload the resulting zip file
It tells me that the file is invalid
Namely, step 2 in the tutorial that is in the link
