There is a report card that our company sends to students. The QR code on the report card was in the pending state, but a 502 error appears.

Url is like this.
"https://chart.googleapis.com/chart?cht=qr&chs=268x268&chld=L|0&chl=https%3A%2F%2Fai.tosel.co.kr%2Fgrade%3Fgradeturn%3D2126%26receipt_no%3D001136830002%26show%3DNaN"
Hurry up and solve it.

The "chart.apis" server that you were using was deprecated for many years, and has finally been turned off.  

The "visualization-api" is an interactive charts library that works quite differently.  Part of that library was a wrapper around the "image charts" which use the "chart.apis" server.
