Postman - newman html report cannot be found in github actions

Question

Im trying to generate a html report while running newman command for my postman collection. But the upload artifact step cannot find the file and I'm getting Warning: No files were found with the provided path: ./newman_report.html. No artifacts will be uploaded.. In fact, this file is nowhere to be found in the directory where this command is executed, I tried with many different paths but report is never there. Report is generated in the correct path when I execute the command locally.

Heres my latest version of the workflow:
