pact-provider-verifier --enable-pending returns non-zero exit code if pending pact has an invalid format

[romainletendart]

Context

I have a pact file which has been badly generated by a consumer test written in javascript which has duplicate headers in one interaction's request e.g.:

        "headers": {
          "Content-Type": "application/json",
          "content-type": "application/json"
        }

When I run pact-provider-verifier --enable-pending on that pact (which has been uploaded on a pact broker beforehand), I get this error:

in `check_for_invalid': Duplicate header found (Content-Type and content-type. Please use a comma separated single value when multiple headers with the same name are required. (Pact::DuplicateHeaderError)

⚠️ But then pact-provider-verifier just stops with a non-zero exit status code even though the pact is marked as:

        "verificationProperties": {
          "pending": true,

Configuration

• Using pact-provider-verifier (1.38.0) through pact-python==2.2.2
