Hi, I was working on a project and while compiling the code the error msg: "Error compiling for board ESP32-WROOM-DA Module" appeared how should i go about it and fix it.
It would be great if the entire error message was posted.

it looks like a name conflict with one of the libraries and another variable/constant thingy.
Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'
Use code tags (the </> icon above the compose window) to make it easier to read and copy for examination
so what should i do how should i fix it
