warning on AzurePipelines PublishTestResults for .coverage file

[huw-dhcw]

I'm trying to run MSTests on azure devops and publish the .coverage file.
I'm don't want to add anything like coverlet at the moment, I'm happy with the coverage file on it's own.
I have the below script which succeeds in publishing the test results but not the coverage. I get the following warning:

##[warning]Unable to archive the test results: Could not find a part of the path 'D:\a\1\a\Tests\VssAdministrator_WIN-KPLQORHEV3_2022-07-01_07_58_09\In\WIN-KPLQORHEV3\VssAdministrator_WIN-KPLQORHEV3_2022-07-01.07_58_04.coverage'..
##[warning]Failed to publish test results: Could not find file 'D:\a\1\a\Tests\VssAdministrator_WIN-KPLQORHEV3_2022-07-01_07_58_09\In\WIN-KPLQORHEV3\VssAdministrator_WIN-KPLQORHEV3_2022-07-01.07_58_04.coverage'..

Any ideas?
