How to fix ArduinoJSON: error: 'DynamicJSONDocument' was not declared in this scope
Problem:
While trying to compile your project, you see an error message like
example.txt
error: 'DynamicJSONDocument' was not declared in this scopeSolution
The Json in DynamicJsonDocument must be spelled camel case: Json, not JSON! The correct spelling is DynamicJsonDocument.
If that does not help, ensure
example.cpp
#include <ArduinoJson.h>is at the top of the file where the error occurs.
