Regarding html page configuration

I am working on esp32 with Platformio in VSCode. In this project, i need to implement html page.
But i don’t know how to make configuration for html page. i have implemented page, and included path also. But while compiling i am getting *** [.pio/build/esp32doit-devkit-v1/.pio/build/esp32doit-devkit-v1/root.html.o] Source .pio/build/esp32doit-devkit-v1/root.html.S' not found, needed by target .pio/build/esp32doit-devkit-v1/.pio/build/esp32doit-devkit-v1/root.html.o’. .
I found no clue for this. Can you guys help me out please?

My platformio.ini file is as below :
platform = espressif32
board = esp32doit-devkit-v1
framework = espidf
monitor_speed = 115200


Looks like you forgot to tell PlatformIO to embed the binary data.

great… it worked… thanks a lot.
