SyntaxError: Identifier 'builders' has already been declared (9:3)

Describe the bug I’m trying to generate code from my ts files with graphql queries, but I get this error:

SyntaxError: Identifier 'builders' has already been declared (9:3)

To Reproduce Steps to reproduce the behavior: I’ve tried to reproduce the error, but I got a new one. in codesandbox I get

TypeError: Cannot read property 'buildError' of undefined

https://codesandbox.io/s/zen-platform-dowef?file=/schema.gql

1. My GraphQL operations:

import { gql } from '@apollo/client';

export const FULL_TASK = gql`
  fragment FullTask on Task {
    id
    title
    isCompleted
    isStarred
    atMyDay
    startDate
    startDateTime
    endDate
    endDateTime
    rrule
    missing
    recurringTaskId
    project {
      id
      title
      icon
      color
      backgroundColor
    }
  }
`;

import { gql } from '@apollo/client';

export const DELETE_TASK_MUTATION = gql`
  mutation deleteTask($taskId: String!) {
    deleteTask(taskId: $taskId) {
      ...FullTask
    }
  }
`;

1. My codegen.yml config file:

overwrite: true
schema: "./schema.gql"
documents:
  - "./**/*.gql"
  - "./**/*.ts"
generates:
  generated.tsx:
    schema: "http://server:3000/graphql"
    plugins:
      - "typescript"
      - "typescript-operations"
      - "typescript-react-apollo"

Expected behavior It should generate code without any errors

Environment:

"@apollo/client": "3.3.11",
"@graphql-codegen/cli": "1.21.4",
"@graphql-codegen/introspection": "1.18.1",
"@graphql-codegen/typescript": "1.21.0",
"@graphql-codegen/typescript-operations": "1.17.14",
"@graphql-codegen/typescript-react-apollo": "2.2.1",

@eden-lane Just ran into a similar issue with leftover/untracked declaration files conflicting with type gen. Try using the DEBUG mode to see where exactly the error is coming from. https://www.graphql-code-generator.com/docs/getting-started/codegen-config#debug-mode

(Maybe just print a warning to the log with the invalid file path, and ignore that file?)

💯 This would be wonderful!
