CLion - running tests with coverage

CLion 2021.1.1

I have a CMake project that contains some doctest tests.  I have a debug build configuration that successfully runs the tests.  I want to run the tests with coverage.

I selected 'Run XXX with Coverage' from the menu.  CLion built the project, stated that no coverage files could be found and offered to fix the build configuration for me.  I accepted the offer.  CLion re-built the project using a newly created 'Debug - Coverage' build profile, but the build failed and continues to fail.  The error message reported is terse:

2021-05-04 10:19:06.886+00:00 [default] [ 2695] error - --id is required

What id is required?  Where should I supply it?  I can find no supporting error messages in the CLion logs (Help |  Show log in files).
