Hi.
Weird… I never got that error before. I’m not sure exactly what it is about…
How does your platformio.ini file looks like?
Do you have all the required files to run the project?

Hi Sara,
Thanks for your reply. I have discovered that there are several ESP Async WebServer libraries. When I include ESP Async WebServer in platform IO it chooses which library to include. I need to check further to make sure it selects the correct library for your code.
Thanks for your help. I will let you know what I find out.

Hi.
You need to include the libraries exactly as we show in the tutorials.

Hi Sara
Could you please give me the full details of the library I must use? If the just put ESP Async WebServer Platform IO will select which one to use. I need the extension info please.

Hi.
Another alternative is to include it like this in your platformio.ini file

lib_deps = https://github.com/me-no-dev/ESPAsyncWebServer.git
 
This is link to the Github library page: https://github.com/me-no-dev/ESPAsyncWebServer
 
I hope this helps.
