'Stripe Direct Payment' works well in our local, but does not work in Azure App Services?

The Stripe payment plugin (Stripe Direct Payment) works well in our local, but does not work in Azure App Services. The code and data are both same. Is it a setting issue? or license issue? Any advice will be appreciated!

Check if the theme uses this widgetzone
PublicWidgetZones.BodyEndHtmlTagBefore

Maybe you removed it.
