UPDATE: This is no longer an issue on v0.6.0, I'll keep it open because it might still be relevant for you, feel free to close in case.
I installed version from master v 0.6.1 downgrading to v 0.6.0 seemed to fix the issue for me
Describe the bug
Getting NO SCHEMA AVAILABLE after activating this plugin in GraphiQL Ide.
Everything was working fine until I activated Gql WooCommerce plugin.
Deactivating it shows the schema back
To Reproduce
Activate both plugins (wp-graphql and wp-graphql-woocommerce) and lookup for the schema or documentation in graphiql, both are empty
Expected behavior
A clear and concise description of what you expected to happen.

Additional context
Add any other context about the problem here.
Just in case I tried to do run a query on products getting it from the documentation:
query MyQuery {
products(first: 1) {
edges {
cursor
node {
id
name
}
}
}
}
And it responds 500
{
"code": "internal_server_error",
"message": "<p>There has been a critical error on your website.</p><p><a href=\"https://wordpress.org/support/article/debugging-in-wordpress/\">Learn more about debugging in WordPress.</a></p>",
"data": {
"status": 500
},
"additional_errors": []
}
Most of the time when this happened to me (maybe doesn't apply to you), logging out/back on seemed to fix this issue. Maybe some important config is stored in the session/cookies and forcing it to refresh it resolves the issue.
I see thanks for the response, I "fixed" it downgrading actually so maybe latest version is not super stable?
Also I noticed that in graphiql I get 500 oftens while calling the endpoint from my app works. Mystery. The problem is I don't know how to debug the wp part unfortunately.
I will try to logout login again thanks maybe it will help, thanks
@dbertella This is due to a breaking change in WPGraphQL v0.14.0. I'll get a hotfix out as soon as I can.
@dbertella This was resolved with the release of WPGraphQL v0.15.0 and this PR in WPGraphQL.
Hi @kidunot89,
I'm facing the same problem in graphiql as well as getting 500 errors when querying to graphql endpoint.
WpGraphql version 1.1.8
Wp-graphql-woocommerce version 0.7.0
Once I deactivate Wp-graphql-woocommerce everything works fine. I was also able to get it working by reverting wpgraphql to version 0.14.0
On the console, I get the following errors:

This is still happening on WP GraphQL 1.2.6 and WooGraphQL (0.8.1) on Wordpress (5.7). Please advise @kidunot89
Hi @kidunot89,
I am also having the same problem after activate the WooGraphQL, I cannot find any schema in GraphQL IDE and when I execute the query, it results wit "Internal Server Error". No other information presented ( GRAPHQL_DEBUG is set to true).
Once I deactivate, everything's back to normal. I am currently using Wordpress 5.7, WP-GraphQL 1.3.5 and WooGraphQL 0.8.1.
Thank you
I am currently seeing this issue with WPGraphQL 1.3.5 if Custom Post Type UI 1.9.1 plugin is enabled.
Latest version of both.
I am also currently seeing this issue with WooGraphQL 0.8.1, WP GraphQL 1.3.8, and WordPress 5.7.1.
I see this error on the console:
invariant.mjs:6
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 }
at r (invariant.mjs:6)
at r (buildClientSchema.mjs:27)
at App.js:181
I am also not seeing any schema when i activate WooGraphQL, no problem when it's desactivated (WooGraphQL 0.8.1, WP GraphQL 1.3.8, and WordPress 5.7.2).
Should I downgrade ?
