Custom config page for Flow Action does not dispatch Remix action requests when using CDN AppBridge

Hello,

While implementing a new app with a custom Action for Shopify Flow, we have encountered an issue.

When the CDN-provided version of AppBridge (v4?) is used on the Custom Config page (based on the Shopify Remix starter template), any Remix Action requests do not perform requests to the server-side.

I have prepare a repository which demonstrates the issue, as well as capturing some of my observations, below:

I’ve also noticed and raised other issues with using the CDN version of AppBridge in Flow.

Is using the CDN version of AppBridge for the custom config page of a Flow action supported/advisable at this point?

Please let me know if you require any further details.

Thanks,

James
