AutomationName produces error ("cant be blank" although it is not blank)

[DanaT1234]

Is there an existing issue for this? I have searched the existing issues

Current Behavior Although an AutomationName is specified, an Error ("OpenQA.Selenium.WebDriverArgumentException: 'automationName' can't be blank") appears when trying to initialize the AppiumDriver

Expected Behavior I expect no errors

Minimal Reproducible Example

1. start appium server

2. Try to initialize AndroidDriver with c# code:

       AppiumOptions capabilities = new AppiumOptions();
       capabilities.AddAdditionalAppiumOption("AutomationName", "UiAutomator2");
       capabilities.AddAdditionalAppiumOption("DeviceName", "Samsung-A52-01");
       capabilities.AddAdditionalAppiumOption("platformName", "Android");
       capabilities.AddAdditionalAppiumOption("browserName", "chrome");
       capabilities.AddAdditionalAppiumOption("PlatformVersion", "12");
       AppiumDriver driver = new AndroidDriver(new Uri("http://localhost:4723"), capabilities, TimeSpan.FromMilliseconds(60000));

3. see Error

Environment Operating system: Windows 10 Appium: 2.0.0-beta.64 Appium.Webdriver: 5.0.0-beta03 Platform and version under test: Android 12 Real device or emulator/simulator: Real device

Futher Information Others seem to have encountered the same issue: https://discuss.appium.io/t/appium-2-with-c/38680/10

[mykola-mokhnach]

The error is valid. Capability names are case-sensitive, so

"AutomationName" -> "UiAutomator2"

is not recognised as valid cap

[DanaT1234]

What should it be instead? "UiAutomator2" is exactly the name that is stated by the Appium Logs. I'm new to Appium, maybe you can clarify what the name should be instead?

[DanaT1234]

Or are you refering to "AutomationName" starting with "A" in my code but with "a" in the Error? I've already tried writing "automationName" instead, but that gets another Error ("System.ArgumentException: There is already an option for the appium:automationName capability. Please use the AutomationName property instead."), so i thought it had to be "AutomationName" and not "automationName"

[laolubenson]

@DanaT1234 have you tried the suggestion provided by the error message, and setting the AutomationName property to UiAutomator2? i.e,capabilities.AutomationName = "UiAutomator2";

[Dor-bl]

AutomationName is already defined as part of the appium options. Just use 'appiumOptions.AutomationName' instead of calling the add additional options method

@laolubenson Thank You! It seems like i have misunderstood the error message. It seems to work now
