Blocks not rendering with JS error in admin

[ad_1]

Hello,

I’ve just set up a Fastspring demo account to test a single page buy button with this plugin. Both on a local development setup and a remote test site (added to the whitelist) I am seeing the same error. I’m on WP 6.0.2 and I’ve tested with the library (and also with 0.8.6 after fresh install of the plugin).

In the admin, adding a “FastSpring Product Catalog” works, but blocks like “FastSpring Buy Buttons” or “FastSpring Checkout Button” give me this error in the admin in the developer console (Firefox 104.0.1):

TypeError: window.prods[Object.keys(...)[0]] is undefined

In the Gutenberg editor it simply says: “This block has encountered an error and cannot be previewed.” In the frontend, nothing renders.

In my PHP error logs I get these, presumably as a result of the block trying to render stuff it couldn’t properly save in the admin:
