GAM Original Api InStream Video Config_ID Ad gives code 999, WARNING: request.imp[0].ext must contain at least one valid bidder

[noureen]

I am trying to run InStream Ad. I cloned the PreBidMobile Android repo and just run the code and open Activity GamOriginalApiInStreamActivity. In this Ad video is being skipped or I do not know it is somehow giving some cache error
after not playing Ad video just jumped to content video part.

Samle code:

class GamOriginalApiInStreamActivity : BaseAdActivity() {

    companion object {
        const val AD_UNIT_ID = "/21808260008/prebid_demo_app_instream"
        const val CONFIG_ID = "prebid-demo-video-interstitial-320-480-original-api"

        const val WIDTH = 640
        const val HEIGHT = 480

        const val VIDEO_URL = "https://storage.googleapis.com/gvabox/media/samples/stock.mp4"
    }

    }

    private fun createAd() {
        // 1. Create InStreamVideoAdUnit
        adUnit = InStreamVideoAdUnit(CONFIG_ID, WIDTH, HEIGHT)

        // 2. Configure video parameters
        adUnit?.videoParameters = configureVideoParameters()

        // 3. Init player view
        playerView = PlayerView(this)
        val params = ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 600)
        adWrapperView.addView(playerView, params)

        // 4. Make a bid request to Prebid Server
