pwa-studio: Could not find a schema at lastCachedGraphQLSchema.json

@LucasCalazans - It appears we’re not allowing insecure backends in query validation, which is why you’re seeing this error. I think it’s reasonable to add the insecure: true flag to packages/venia-concept/.graphqlconfig so this validation works with self-signed certificates, especially since we only expect to validate queries in development environments (skipped in production builds). I’ll update the issue description with this proposed fix.

In the meantime, if you change your MAGENTO_BACKEND_URL to http, this should get around the error, or you can manually add this flag to .graphqlconfig.

Edit: I’m actually going to create a new issue for this, since it’s different from the originally reported issue and few other comments in this thread. See #1311.

I think that the error I’m getting is the same reported:

✖ An error occurred:
Could not find a schema at lastCachedGraphQLSchema.json.

Edit: Yes, this error was about the certificate. I’ve changed to HTTP and it has worked. Thanks @tjwiebell

Same issue here. Magento -> 2.3.1 PWA-Studio -> develop SO -> Fedora 26
