I have a problem about YouTube API with ESP8266 - api

Question

I try to make youtube subscribe counter but it a problem with youtube api library here the error message
Arduino: 1.8.12 (Windows 10), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), 2, v2 Lower Memory, Disabled, None, Only Sketch, 115200"
The sketch name had to be modified.
Sketch names must start with a letter or number, followed by letters,
numbers, dashes, dots and underscores. Maximum length is 63 characters.

I already download youtube api library and arduino json library and import it to arduino ide I always get error from it i dont know why it gone like this someone who know please help me. I like to hear from you.
And here my code :

I would ditch the libraray - it uses
#include <ArduinoJson.h>
and the error tells us whats wrong
error: DynamicJsonBuffer is a class from ArduinoJson 5 <=== you have probably version 6.x.x installed
which is a memory hog. Often one single function is used by libraries and the rest is useless. To solve your problem, you have to
downgrade ArduinoJson.h to version 5.13.5
The other reason I do not like it, breaking changes in nearly all major releases (real big breaking). So another option you have (if skilled enough) replace the ArduinoJson functions with
a lighter JSON library
or replace it with self written JSON functions - often a simple buffer and some char handling does the trick
Read the issues and PRs on github to inform yourself about missing updates and other problems. Development stopped March 2018 since then no adaption to the (breaking) changes in the youtube API
