Integration tests for `/api/v1/task/classification-with-text-generation` endpoint

[mdevino]

Description

As an orchestrator developer, I want to have integration tests for the /api/v1/task/classification-with-text-generation endpoint, so that I can make changes and make sure I am not breaking existing logic.

Discussion

I would start this story with just creating and test case for the "success" case, then create other stories for handling error cases.

Acceptance Criteria

• [ ] Unit tests cover new/changed code
• [ ] Examples build against new/changed code
• [ ] READMEs are updated
• [ ] Type of semantic version change is identified
