com.testdroid.api.APIException: Failed to submit test run! No device model matching pattern

I'm New to bit-bar. I'm trying to automation mobile native application, When run my test case with below desired capabilities, I'm getting 

Message: com.testdroid.api.APIException: Failed to submit test run! No device model matching pattern '%Samsung Galaxy A50 2019 SM-A505FN' available

My Desired capabilities:

{"bitbar_apiKey": "<my Key>", "bitbar_device": "Samsung Galaxy A50 2019 SM-A505FN",
                "bitbar_app": "<my app id>", "platformName": "Android", "appPackage": "com.aws.android",
                "appActivity": "app.ui.HomeActivity", "deviceName": "Android Phone",
                "bitbar_project": "WB-BitBar-POC", "bitbar_testrun": "Scree",
                "automationName": "uiautomator2", 'appPackage': 'com.aws.android',
                'appActivity': 'app.ui.HomeActivity'}

I have tried both driver = webdriver.Remote("https://us-west-mobile-hub.bitbar.com/wd/hub", capabilities) and
browser.driver = webdriver.Remote("https://appium.bitbar.com/wd/hub", capabilities)

 Any help on this would be appreciated.
