NO SCHEMA AVAILABLE in GraphQL IDE

[LarsEjaas]

I get the error:
NO SCHEMA AVAILABLE in the left side of the GraphQL IDE if I activate the wp-graphql-gutenberg plugin in WordPress. Are there any known issues or incompatibilities here I need to be aware of? I have updated all plugins to the recent version.

@LarsEjaas I believe that you may have to go to "GraphQL Gutenberg" in the admin panel and press the "Update block registry" button.

I think I see the same thing on a fresh WordPress install. Not sure if there is another fix for it than manually updating the block registry.

Also getting this error when GraphQL Gutenberg is installed. This error is thrown in the browser console on the GraphiQL IDE:

Uncaught (in promise) Error: Invalid or incomplete introspection result. Ensure that you are passing "data" property of introspection response and no "errors" was returned alongside: { status: 500 }.

Same issue here, I am getting an error 500 :
https://URL/index.php?graphql 500 (Internal Server Error)

After install the plugin, clicked on update block registry, and then navigate ton GraphiQL IDE
I installed v0.3.12, but it show v0.3.11 in wordpress back-office
