Live Preview Not Working

[levinelson]

Description

Upgraded to Craft 4 a month or so ago, and just realize Live Preview does not seem to work when editing Digital Products. Live Preview is working when editing other vanilla Craft entries.

Steps to reproduce

1. Open a digital product entry page in CP
2. Click "Live Preview"
3. In the console, I see a Failed to load resource: the server responded with a status of 500 () for something like https://path-to-entry?token=-h7B4f57cIfo_IHiWnP6l54NGNYsept8.
4. Going to that URL above also says Bad Request Post request required.

Additional info

• Craft version: Craft Pro 4.3.7
• PHP version: 8.0.27
• Database driver & version: MySQL 8.0.32
• Plugins & versions: Commerce 4.2.5.1, Digital Products 3.2.0

This was fixed in 3.2.1 Thanks.

Hi, I'm still seeing this same error using 3.2.1 when trying to live preview a digital product.
