Error while creating overlay

Hi,
I am trying to create an overlay with the help of the tutorial: Overlay Tutorial — Python productivity for Zynq (Pynq) v1.0
youtube link: Create a custom PYNQ overlay for PYNQ-Z1 - FPGA Developer

I am using pynq z2 board and vivado 2021.2
I have placed .tcl,.bit and .hwh files on the zynq board.

I am getting error:

Where did it go wrong and what should I do to resolve this error?

Lets make sure 1 very basic setting:
What is the Vivado project device you had set?
XC7Z010 or XC7Z020?

Enjoy~

It’s XC7Z020

@riah

Post out the folder capture of the files you are using via explore or any terminal.
What are the names of these files and the path of these files.

Enjoy~

Can you post a screenshot of your block diagram?

On pynq board:

In file explorer:

@riah

Put your script in the same folder of these file.
change the Overlay path to ‘adder.bit’
Try if this is working.

While did you import all the necessary packages?

Enjoy~

I made changes as you have mentioned but I am still facing the same issue.
And can you once tell what the necessary packages means?

@riah

from pynq import Overlay

BTW what PYNQ version you are using?
2.7 or 3.0.1?

I will highly suggest you attach the hwh here to let us investigate what is the possible issue.

Enjoy~

I am using 3.0.1 version
@briansune sure, I will attach the file here.

@riah

I had asked you and you do said you set to XC7Z020.

Enjoy~

I am really sorry.
I made sure that I use xc7z020 only. I am not aware of how I made that mistake.
I will try again. Thankyou for your time and once again I apologize.
