CircleCi and CodeCov: The '<' operator is reserved for future use

Question

I am trying to integrate CodeCov in CircleCI, but the command

bash <(curl -s https://codecov.io/bash)

returns

The '<' operator is reserved for future use. when executed in the pipeline.

I am following the documentation that I found for

• CodeCov: https://docs.codecov.io/v4.3.0/docs/about-the-codecov-bash-uploader
• CircleCI: https://circleci.com/docs/reference-2-1/#jobs

My config.yml has the following steps:

steps:
      - checkout
      - run:
          name: "Run Unit Tests"
          command: dotnet.exe test ./UnitTests --collect:"XPlat Code Coverage"
      - run:
          name: Upload CodeCov.io Data
          command: bash <(curl -s https://codecov.io/bash)
          when: always # Uploads code coverage results, pass or fail

I have also tried with just curl -s https://codecov.io/bash but in this way I get the error Invoke-WebRequest : Cannot process command because of one or more missing mandatory parameters: Uri.

Has anyone of you made this integration?

Thank you

Update:

I had to add the .exe to the curl command:

- run:
    name: Upload Coverage Results
    command: curl.exe -s https://codecov.io/bash | bash -s --
    when: "always"

Now it builds but can't find the report.
