[Typescript] "No matching export ..." error for PIPEDRIVE.COM api

Nobody has claimed this yet.

Found as part of https://github.com/microsoft/kiota/pull/7774:

Using the source code from 2026-06-17 and this command:

```
.\it\generate-code.ps1 -descriptionUrl https://developers.pipedrive.com/docs/api/v1/openapi.yaml -language typescript -dev
.\it\exec-cmd.ps1 -descriptionUrl https://developers.pipedrive.com/docs/api/v1/openapi.yaml -language typescript
```

The generated client does not compile:

```
X [ERROR] No matching export in "src/app/client/oauth/token/index.ts" for import "createPostResponseFromDiscriminatorValue"

```

This is the error line in "app\client\oauth\token\index.ts":
```typescript
import { createPostResponseFromDiscriminatorValue, serializePostRequestBody, serializePostResponse, type PostRequestBody, type PostResponse } from './index.js';
```

And this is the error line in "app\client\oauth\index.ts":
```typescript
import { EmptyPathSegmentRequestBuilderRequestsMetadata, TokenRequestBuilderNavigationMetadata, TokenRequestBuilderRequestsMetadata, type TokenRequestBuilder } from './token/index.js';
```

It is caused by the endpoint `/oauth/token/` ("Refreshing the tokens"), but I don't see anything special here:

```yaml
/oauth/token/:

Run the two commands in the issue with the Pipedrive OpenAPI URL and inspect the generated app/client/oauth/token/index.ts and app/client/oauth/index.ts files. Trace the /oauth/token/ endpoint through generation, then verify that the generated TypeScript client compiles without the reported missing exports and metadata imports.
