Dexter seems to fail when loading a customer application (UWM, MuleSoft Application)

**Describe the bug**
While doing a SaaS controller migration planning exercise for United Wholesale Mortgage, we took configuration and metadata dumps for a non-production and production controller.

Non-production DEXTER extracts worked without issue
Production repeatedly failed, stopping in the middle of dumping an app in the middle of their applications at an app called "Mulesoft".

Dexter throws and error, then stops processing, and stops generating CSV files.

We have extracted the application configuration using ConfigExporter, hoping that the problem will replicate in another controller after loading. (JSON attached)

**To Reproduce**
Steps to reproduce the behavior:
1. Load this Mulesoft.JSON
2. Adapt the UnitedShoreJob file to fit your controller
3. Run the DEXTER job to attempt to load Mulesoft
4. See error

**Expected behavior**
DEXTER stops generating output files and cancels remaining job steps including report generation.

- .NET Framework Type (Full/Core)
- .NET/.NET Core Framework Version

**Logs**
Add logs from the program execution https://github.com/Appdynamics/AppDynamics.DEXTER/wiki/Log-Files

**Reports**
Include any produced reports that you have issues with

Start by loading Mulesoft.JSON and adapting the UnitedShoreJob as described, then run the DEXTER job and capture the execution logs. Compare the failing application load with the successful extracts; the issue's expected behavior is inconsistent with the reported failure, so the intended outcome needs clarification before defining done.
