Sending code for error detection facing problem with error not able to compile code
Probably the main problem is already in the first lines:

#include ESP8266WiFi.h
#include LiquidCrystal.h
#include FirebaseArduino.h&gt;
#include HX711.h&gt;


You should use the correct formatting:

#include "ESP8266WiFi.h"
#include "LiquidCrystal.h"
#include "FirebaseArduino.h"
#include "HX711.h"


Also, HX711 does not have a constructor with arguments, so instead of

HX711 scale(DOUT, CLK);


uese

HX711 scale;


and in Setup:

scale.begin(DOUT, CLK);


You probably have the code meant for a different library.

See HX711_full_example. Or use the code belonging to your used HX711 library.
