Odd Exception Not Sure where to look

[jazzmasta25]

I am getting an odd exception and I am not sure where else to look:

An unhandled exception occurred while processing the request. MissingMethodException: Constructor 'Microsoft.AspNetCore.Http.IFormFile()' was not found. CsvHelper.ObjectCreator.GetConstructorNotFoundException(Type type, Type[] argTypes)

I am using the latest version of CsvHelper.

Any help would be greatly appreciated.
