A schema MUST have a 'query' operation defined Error. But I have type Query in my schema.

[tintin10q]

I have added my schema to a .graphql file in my main project directory. I now get this error:

This is very weird because I do have a type Query {} in my .graphql file with multiple queries in there. When I copied the Query type into an empty .graphql file and I changed all the return types to strings I did not get the error anymore.
To Reproduce
I don't really know how you could reproduce this I don't want really share my schema.

Expected behavior
I don't expect a 'A schema MUST have a 'query' operation defined' error to pop up when there is a type Query in the schema

Version and Environment Details
Operation system: Win 10
IDE name and version: Webstorm 2020.3.2
Plugin version: 2.9.1

Same here

Please could you bubble up the error message from parsing the file? At least if we know a line number of the .graphql that is causing the issue, I could open a better issue with a more exact feature request.

Sorry but I am not sure what you mean with bubble up the error message from parsing the file.

[binary64]

I feel the graphql parser used from your plugin is not liking my schema.graphql (>100k lines). I've tried snipping off random bits in an attempt to narrow down what is causing the issue (for example enum's), but no luck so far. What I ideally need is to see the inner exception - something like "Unexpected token on line 178937".

It feels like the parse happened inside a try/catch block, and it silently failed, causing the schema to have no query (the error I see).

@binary64 I ran into the same error as well. Do you use a schema inside the node_modules folder?

[eugene1g]

I struggled with the same error for a while. Then I accidentally deleted the project from IntelliJ and removed all hidden IDE subfolders, and when I re-added the same project folder back to WebStorm the plugin worked perfectly again. Worth a try :)

Unfortunately, this is a common error that occurs when the schema could not be built for some reason. I've improved error handling and logging in the upcoming version that I'll release soon.

I experience this issue on Webstorm 2021.3.2 and plugin version 3.1.2, even with the simplest example of relay-schema.graphql and .graphqlconfig:

@goktugerce
Temporary solution is install plugin version 3.0.0 from https://plugins.jetbrains.com/plugin/8097-graphql/versions

[segfaultDelirium]

@Mozzarella123 I tried, and it didn't help.

Same Problem.
Schema is generated but Schema discovery summary says "schema is empty".
Any help?
Webstorm 2022.2.2 and GraphQl 3.3.0

I'm also bumping into this with a small schema:

# This file was generated based on ".graphqlconfig". Do not edit manually.

schema {
    query: Query
}

interface ContentNode {
    _meta: ContentNodeMetaData
    rawJson: ContentItemJson
    rawProperty(propertyName: String!): JSON
}

type ContentItemJson {
    content: JSON
}

type ContentNodeMetaData {
    deliveryId: String!
    deliveryKey: String
    name: String
    schema: String!
}

type PageInfo {
    endCursor: String
    hasNextPage: Boolean!
    hasPreviousPage: Boolean!
    startCursor: String
}

type Query {
    allStaticPage(after: String, before: String, first: Int, last: Int): StaticPageConnection
    allWebConfig(after: String, before: String, first: Int, last: Int): WebConfigConnection
    contentNode(deliveryId: String, deliveryKey: String): ContentNode
    staticPage(deliveryId: String, deliveryKey: String): StaticPage
    webConfig(deliveryId: String, deliveryKey: String): WebConfig
}

type StaticPage implements ContentNode {
    _meta: ContentNodeMetaData
    articleContent: String
    rawJson: ContentItemJson
    rawProperty(propertyName: String!): JSON
    slug: String
    title: String
}

type StaticPageConnection {
    edges: [StaticPageEdge]!
    pageInfo: PageInfo!
}

type StaticPageEdge {
    cursor: String!
    node: StaticPage
}

type WebConfig implements ContentNode {
    _meta: ContentNodeMetaData
    rawJson: ContentItemJson
    rawProperty(propertyName: String!): JSON
    social: WebConfigSocial
}

type WebConfigConnection {
    edges: [WebConfigEdge]!
    pageInfo: PageInfo!
}

type WebConfigEdge {
    cursor: String!
    node: WebConfig
}

type WebConfigSocial {
    facebook: String
    twitter: String
}

"A JSON scalar"
scalar JSON

Corresponding .graphqlconfig:

{
  "name": "GraphQL Schema",
  "schemaPath": "schema.graphql",
  "extensions": {
    "endpoints": {
      "GraphQL Schema": {
        "url": "https://<redacted>/graphql",
        "headers": {
          "X-Src-Host": "<redacted>"
        },
        "introspect": false
      }
    }
  }
}

Error: A schema should have a 'query' operation defined with plugin version 3.3.0.

In my case, .graphql files were not associated with the .graphql file type.

Once I associated them (right-click on the unassociated example.graphql file) I refreshed the .graphqlconfig and re-fetched the introspection schema.

After that everything started to work as before.
