Cannot use Preview Webhook URL with Gatsby Refresh Endpoint on Gatsby 3.7.1

[thinkflo]

Description

According to gatsbyjs/gatsby#10328, setting an env var ENABLE_GATSBY_REFRESH_ENDPOINT=true while running gatsby develop will configure the develop server to re-source data when it receives a POST request to /__refresh.

Based on your documentation on setting up LivePreview in local development, this endpoint needs to be added to the Preview Webhook URL of this Helper. However, this triggers a Get Request which will 404 on the development server, since Gatsby will only accepts a Post request.

Steps to reproduce

1. Install Gatsby 3.7.1 and gatsby-source-graphql 3.8.0
2. Follow all the steps to setup livePreview
3. Make changes in livePreview and see all of the /__refresh calls produce 404 errors because they are not Post requests

Additional info

• Craft version: 3.6.17
• PHP version: 7.4
• Database driver & version: mariadb:10.3
• Plugins & versions: Gatsby Helper 1.0.4

Can you share your Gatsby Helper settings? The updates are definitely leaving Craft as a POST request (

gatsby-helper/src/Plugin.php

Line 233 in eeca60f

http.open('POST', "$previewWebhookUrl", true);

)
