Describe the bug

When I generate my typescript client with Kiota.Builder 1.14 (indirectly through FastEndpoints.ClientGen.Kiota), the resulting typescript files are missing the imports of UntypedNode and createUntypedNodeFromDiscriminatorValue from @microsoft/kiota-abstractions.

Here is an example of a file

/* tslint:disable */
/* eslint-disable */
// Generated by Microsoft Kiota
// @ts-ignore
import { createDomainExceptionResponseFromDiscriminatorValue, createGetWishlistResponseFromDiscriminatorValue, serializeAddToWishlistRequest, serializeDeleteFromWishlistRequest, type AddToWishlistRequest, type DeleteFromWishlistRequest, type DomainExceptionResponse, type GetWishlistResponse } from '../../../../models/';
// @ts-ignore
import { type BaseRequestBuilder, type Parsable, type ParsableFactory, type RequestConfiguration, type RequestInformation, type RequestsMetadata } from '@microsoft/kiota-abstractions';

/**
 * Builds and executes requests for operations under /api/users/{userCodeOr-id}/wishlist
 */
export interface WishlistRequestBuilder extends BaseRequestBuilder<WishlistRequestBuilder> {
    /**
     * @param body The request body
     * @param requestConfiguration Configuration for the request such as headers, query parameters, and middleware options.
     * @returns {Promise<UntypedNode>}
     * @throws {DomainExceptionResponse} error when the service returns a 422 status code
     */
     delete(body: DeleteFromWishlistRequest, requestConfiguration?: RequestConfiguration<object> | undefined) : Promise<UntypedNode | undefined>;
    /**
     * @param requestConfiguration Configuration for the request such as headers, query parameters, and middleware options.
     * @returns {Promise<GetWishlistResponse>}
     * @throws {DomainExceptionResponse} error when the service returns a 422 status code
     */
     get(requestConfiguration?: RequestConfiguration<object> | undefined) : Promise<GetWishlistResponse | undefined>;
    /**
     * @param body The request body
     * @param requestConfiguration Configuration for the request such as headers, query parameters, and middleware options.
     * @returns {Promise<UntypedNode>}
     * @throws {DomainExceptionResponse} error when the service returns a 422 status code
     */
     post(body: AddToWishlistRequest, requestConfiguration?: RequestConfiguration<object> | undefined) : Promise<UntypedNode | undefined>;
    /**
     * @param body The request body
     * @param requestConfiguration Configuration for the request such as headers, query parameters, and middleware options.
     * @returns {RequestInformation}
     */
     toDeleteRequestInformation(body: DeleteFromWishlistRequest, requestConfiguration?: RequestConfiguration<object> | undefined) : RequestInformation;
    /**
     * @param requestConfiguration Configuration for the request such as headers, query parameters, and middleware options.
     * @returns {RequestInformation}
     */
     toGetRequestInformation(requestConfiguration?: RequestConfiguration<object> | undefined) : RequestInformation;
    /**
     * @param body The request body
     * @param requestConfiguration Configuration for the request such as headers, query parameters, and middleware options.
     * @returns {RequestInformation}
     */
     toPostRequestInformation(body: AddToWishlistRequest, requestConfiguration?: RequestConfiguration<object> | undefined) : RequestInformation;
}
/**
 * Uri template for the request builder.
 */
export const WishlistRequestBuilderUriTemplate = "{+baseurl}/api/users/{userCodeOr%2Did}/wishlist";
/**
 * Metadata for all the requests in the request builder.
 */
export const WishlistRequestBuilderRequestsMetadata: RequestsMetadata = {
    delete: {
        uriTemplate: WishlistRequestBuilderUriTemplate,
        responseBodyContentType: "text/plain;q=0.9",
        errorMappings: {
            422: createDomainExceptionResponseFromDiscriminatorValue as ParsableFactory<Parsable>,
        },
        adapterMethodName: "send",
        responseBodyFactory:  createUntypedNodeFromDiscriminatorValue,
        requestBodyContentType: "application/json",
        requestBodySerializer: serializeDeleteFromWishlistRequest,
        requestInformationContentSetMethod: "setContentFromParsable",
    },
    get: {
        uriTemplate: WishlistRequestBuilderUriTemplate,
        responseBodyContentType: "application/json",
        errorMappings: {
            422: createDomainExceptionResponseFromDiscriminatorValue as ParsableFactory<Parsable>,
        },
        adapterMethodName: "send",
        responseBodyFactory:  createGetWishlistResponseFromDiscriminatorValue,
    },
    post: {
        uriTemplate: WishlistRequestBuilderUriTemplate,
        responseBodyContentType: "text/plain;q=0.9",
        errorMappings: {
            422: createDomainExceptionResponseFromDiscriminatorValue as ParsableFactory<Parsable>,
        },
        adapterMethodName: "send",
        responseBodyFactory:  createUntypedNodeFromDiscriminatorValue,
        requestBodyContentType: "application/json",
        requestBodySerializer: serializeAddToWishlistRequest,
        requestInformationContentSetMethod: "setContentFromParsable",
    },
};
/* tslint:enable */
/* eslint-enable */

Expected behavior

The import should include UntypedNode and createUntypedNodeFromDiscriminatorValue

Hi @LaurentVandenbosch
Thank you for using kiota and for reaching out.
Can you try with version 1.15 and tell us if you are still seeing the issue please?

[LaurentVandenbosch]

Hello @baywet ,

The issue is still present with 1.15. I have to use 1.12 to not have this issue, because it doesnt use UntypedNode.
