I corrected your generator code and it works.

      // BackgroundQuery Hook
      const backgroundOperationName: string =
        this.convertName(nodeName, {
          suffix: pascalCase('BackgroundQuery'),
          useTypesPrefix: false,
        }) + this.config.hooksSuffix;

      hookFns.push(
        `export function use${backgroundOperationName}(baseOptions?: ${this.getApolloReactHooksIdentifier()}.BackgroundQueryHookOptions<${operationResultType}, ${operationVariablesTypes}>) {
             const options = {...defaultOptions, ...baseOptions}
             return ${this.getApolloReactHooksIdentifier()}.useBackgroundQuery<${operationResultType}, ${operationVariablesTypes}>(${this.getDocumentNodeVariable(
          node,
          documentVariableName,
        )}, options);
           }`,
      );
      hookResults.push(
        `export type ${backgroundOperationName}HookResult = ReturnType<typeof use${backgroundOperationName}>;`,
      );

      // ReadQuery Hook
      const readOperationName: string =
        this.convertName(nodeName, {
          suffix: pascalCase('ReadQuery'),
          useTypesPrefix: false,
        }) + this.config.hooksSuffix;

      hookFns.push(
        `export function use${readOperationName}(backgroundQueryRef: ${this.getApolloReactHooksIdentifier()}.QueryReference<${operationResultType}>) {
          return ${this.getApolloReactHooksIdentifier()}.useReadQuery<${operationResultType}>(backgroundQueryRef);
        }`,
      );

      hookResults.push(
        `export type ${readOperationName}HookResult = ReturnType<typeof use${readOperationName}>;`,
      );
