Issue description:
Getting a below error while saving a host configuration when there is no other host with the same name.

Troubleshooting steps:
- Check the configuration path of Module Designer in web.config

- Check the ModuleJsonPaths, SimulationURL, HostConfigurationApiURL and JsonFilesURL in <ModuleDesigner-installPath>/Data/MasterData/ApplicationConfiguration.json

Solution:
Make sure all the URLs are valid and path configured are correct.
