Error loading main.py to MicroPython on NodeMCU Lilin V3

Question

I have a NodeMCU board and I'm trying to use it for IoT. I'm using mac and this is the commands I'm using to install MicroPython:

esptool.py --port /dev/cu.usbserial-110 erase_flash esptool.py --port /dev/cu.usbserial-110 --baud 115200 write_flash --flash_size=detect 0 sp8266-512k-20220618-v1.19.1.bin

The installation looks to work fine, I can even access the REPL but then, to load the main.py file I want it to run, I do:

ampy --port /dev/cu.usbserial-110 -b 115200 put main.py

And I get the following error:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.10/bin/ampy", line 8, in <module>
    sys.exit(cli())

I have tried to reset the board many times, be sure that the screen command I used to connect the REPL is not in progress anymore, and even different baud rates, but nothing is working...

Any idea?

Thank you so much!
