You probably try to assign some object to a nlohmann::json value and the library does does not find a to_json function for this conversion.

Example:

MyObjectType foo;
nlohmann::json j = foo; // this line would generate the error like above

See https://github.com/nlohmann/json#arbitrary-types-conversions for more information on how to provide a to_json function.
