When you try to use the configuration.json file in one project and set the startup project as another project. You will come across this error.
The error stack might be somewhat different for you based on your implementation but the solution will be the same. Right-click on the configuration.json file and click on Properties. This solution uses Visual Studio.
Check the property Copy to Output Directory. It might be Do not copy. Change this to Copy always.
