There was a bug in Chart.js version 4 and later.
Therefore, the UMD version that can be used for Kintone customization was added to the Kintone CDN.

Chart.js

• versions: 4.4.0
  https://js.kintone.com/chartjs/v4.4.0/chart.umd.js

Versions to be distributed in UMD version

• versions: v4.4.0
• versions: v4.3.2
• versions: v4.3.0
• versions: v4.2.1
• versions: v4.2.0
• versions: v4.1.1
• versions: v4.0.1

Note

Chart.js URL that has already been published can still be used.
However, the distribution of Chart.js will be stopped after v4.4.0.
