Hello @m2mlorawan
It is caused by the ESP8266 library version.
Oldest tested version is v2.6.3. Latest tested version is 2.7.1 ... you can find it under tools --> Board --> Board Manager
Search for that text here:

Another work around is to update this library:

Please add that version info in your readme file. Your program doesn't compile on esp8266 v3.7.1
