use of "appcenter test run uitest ... --merge-nunit-xml blah.xml" results in error

[jmegner]

If I run the following command, it works and I get a nunit_xml_zip.zip containing a nunit report xml file for each device:

appcenter test run uitest `
    --app "JacobEgnerDemos/XamarinPipelineDemo" `
    --app-path (gci -Recurse "..\*Signed.apk")[0].FullName `
    --devices "JacobEgnerDemos/two_devices" `
    --test-series "master" `
    --locale "en_US" `
    --build-dir "..\XamarinPipelineDemo.UITest\bin\Release" `
    --uitest-tools-dir "..\XamarinPipelineDemo.UITest\bin\Release" `
    --test-output-dir "." `

If I add --merge-nunit-xml "AppCenterUiTestResult.xml" to the command, I still get the zip file containing device-specific xml files but I also get this error message:

Error: The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received an instance of Document

Further error details: For help, please send both the reported error above and the following environment information to us by going to https://appcenter.ms/apps and opening a support ticket (using the help menu in the upper right corner of the screen)


    Environment: win32
    App Upload Id: JacobEgnerDemos/XamarinPipelineDemo

    Operation: RunUITestsCommand
    Exit Code: 3

I was hoping the --merge-nunit-xml argument would get me a single merged xml file.
