Printing monitor mini display

What is the problem?
I keep getting this error while trying to upload a sketch to my D1 mini Nodemcu. Im trying to make a Mini printer monitor display. As shown in this video by chris basement

but i keep getting this error

Arduino: 1.8.12 (Windows Store (Windows 10), Board: "WEMOS D1 mini, 160 MHz, 80MHz, DIO, 115200, 1M (256K SPIFFS)"

In file included from sketch\Settings.h:48:0,

             from C:\Users\Aaron\Desktop\Printer monitor\printer-monitor-master\printermonitor\printermonitor.ino:31:

OctoPrintClient.h:30:20: fatal error: base64.h: No such file or directory

#include <base64.h>


compilation terminated.

exit status 1
base64.h: No such file or directory

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

What did you already try to solve it?
making sure i had the correct libraries and double checking all the steps.

Logs (octoprint.log, serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible)

Hi @award0586,
did you already raise your question on the Print-Monitor Homepage?

There is a "Question-Link" you can use.

For me, it looks like you didn't include base64 in your library-section. Just add that lib via the Arduino IDE.

Please try to limit posting the same question to one thread.

I only posted the question 1 time
