Something went wrong Failed to load schema for "graphql/"

Question

After I run command yarn gen it is giving me this error :

Something went wrong Failed to load schema for "graphql/" Failed to load schema from http://localhost:1337/graphql:

fetch failed TypeError: fetch failed at Object.processResponse (node:internal/deps/undici/undici:5570:34) at node:internal/deps/undici/undici:5896:42 at node:internal/process/task_queues:140:7 at AsyncResource.runInAsyncScope (node:async_hooks:202:9) at AsyncResource.runMicrotask (node:internal/process/task_queues:137:8) at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

GraphQL Code Generator supports:

• ES Modules and CommonJS exports (export as default or named export "schema")
• Introspection JSON File
• URL of GraphQL endpoint
• Multiple files with type definitions (glob expression)
• String in config file

Try to use one of above options and run codegen again.

here is my homepage.graphql

query HomePage {
  homePage {
    data {
      attributes {
        sections {
          ... on ComponentCommonHeader {
            id
            Text
            ButtonText
            ButtonLink
          }
          ... on ComponentCommonCarousel {
            id
            Item
          }
          ... on ComponentCommonTwoColumnBlock {
            id
            TitleText
            Description
            ButtonText
            ButtonUrl
            ImagePosition
            Image
          }
        }
      }
    }
  }
}

and here is my graphql.config.yml:

overwrite: true
schema:
  - http://localhost:1337/graphql
documents: "graphql/**/*.graphql"
generates:
  graphql/types.tsx:
    plugins:
      - "typescript"
  graphql/:
    preset: near-operation-file
    presetConfig:
      extension: .generated.tsx
      baseTypesPath: types.ts
    plugins:
      - "typescript-operations"
      - "typescript-react-apollo"
    config:
      withHooks: true

I ran into this and fixed it by replacing localhost with 127.0.0.1. Other solution that you may want to try is to delete node_modules and package-lock.json and to reinstall dependencies.
