this is my command - pactflow publish-provider-contract C:/Users/srinivasraghupatruni/Downloads/personDetailsQueryOpenApi.json --content-type=application/json --provider=plexus --branch=test-pactflow-command --broker-base-url=https://makeit.pactflow.io/ --provider-app-version=0.0.1 --broker-token={broker token} --verification-success --verification-results=C:/Users/srinivasraghupatruni/Downloads/results.yml --verification-results-content-type=application/yaml --verifier=handmatig

Can you capture the call that is being made to your broker using Fiddler or something similar and post it here?

Now I'm able to publish provider contract without any error. This error has come due to an empty restults.yml file. I've added junit results file to resolve this error.
