NX WebServer CubeMX Exemple not work get FX media opening failed: 0x21

When trying to run the webservice example for the STM32-F429ZI-Cube board, I'm getting the following error:

Nx_WebServer Application started..

IpAddress: 192.168.23.100

FX media opening failed : 0x21

There's nothing about this error in the README.md file, it suggests that I should write to RAM with the command <INSTALL_PATH>STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe -c port=swd -w <INSTALL_PATH>web_content\web_demo.bin

But I can't find the web_demo.bin file

I tried with chatGPT, but it took me down a darker path and away from the solution :)

What am I doing wrong in this example?

I'm searching on Google, but I always end up in the same places, that the problem is the lack of some file saved in memory, and this file is in bin format, but I can't find the command in my installation, and I can't find how to install it. Furthermore, the code generated during compilation does not generate any .bin file.
