Fix runtime error in the API

[ValentaTomas]

Background

I found a runtime error in the API mainly caused by a wrong variable access.

Changes

The changes I made are in the cli_web_app directory - I fixed the error and updated the files to work with some changes to the other parts of AutoGPT.

Documentation

I need to document the changes and the new functionality.

Test Plan

I still need to thoroughly test these changes.
