Conversion from 'const uint8_t {aka const unsigned char}' to 'String' is ambiguous

Anyone can help me with this problem ?

//=====Library=====//
#include <MQUnifiedsensor.h>
#include <DS3231.h>
#include <SD.h>
#include <SPI.h>
#include <OneWire.h>

#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);
DS3231 rtc(SDA, SCL);
File myFile;
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);

MQUnifiedsensor mq8(MQ8_WIRE) Here the problem

int minSmokePPM = 5000;

‘const uint8_t {aka const unsigned char}’ to ‘String’ is ambiguous](Conversion from 'const uint8_t {aka const unsigned char}' to 'String' is ambiguous)

if the above is an error msg, why don’ t you include the line number?

Please use code tags.

Look at MQUnifiedsensor .h and see what the prototype for mq8() is expecting for an argument.
