Completed Q&A, but move2kube API thinks there are more questions and transformation fails

[y-first]

Describe the bug
After completing the Q&A by answering all the questions, the Q&A window closes and a "transformation completed" notification pop up appears in the Move2kube UI. However, the move2kube api thinks there are more questions but at that stage the QA engine is not running anymore, and the transformation fails. The following error appears in the move2kube pod logs:

Steps to reproduce the behavior:

1. Deploy move2kube
2. Click on Q&A and answer questions
3. After answering final question, Q&A window closes itself and "transformation finished" pop up appears
4. See above error in move2kube pod logs

Expected behavior
Expected transformation to complete normally.

Desktop (please complete the following information):

Version: using move2kube image quay.io/konveyor/move2kube-ui:v0.3.14-rc.0

Additional context
The completed files appear and are downloadable in the "output" section.

Is the following the error you want to avoid?

time="2024-08-22T08:16:09Z" level=error msg="failed to get the next question. Error: "failed to send a GET request to the URL http://localhost:41895/problems/current . Error: "Get \"[http://localhost:41895/problems/current\\\](http://localhost:41895/problems/current%5C%5C%5C%5C%5C%5C%5C)": dial tcp [::1]:41895: connect: connection refused""" request-id=6befb2d7-27d9-4f43-b570-aa6bc5dfb354

Yes. It's odd since according to the logs, the transformation had already completed, so why is it trying to get to the next question?

Could it be possible that this is a regression in error handling bug in the move2kube-api, possibly caused by 273206c ?

@HarikrishnanBalagopal please correct me if I am wrong. But I think it is because the url is served by the cli, whose QA server gets terminated when the last question is done, and I think we are just logging it even though it is the natural flow.
