[🐛 Bug]: driver.Manage().Cookies.AddCookie(); with Native aot(c#)

[katanakatana123]

What happened?

when i use driver.Manage().Cookies.AddCookie(); i got the error OpenQA.Selenium.WebDriverArgumentException: invalid argument: missing 'name',
i think the problem comes from here

selenium/dotnet/src/webdriver/WebDriver.cs

Line 567 in b16d0d8

protected virtual Response Execute(string driverCommandToExecute, Dictionary<string, object> parameters)

, when native aot cannot resolve json class

How can we reproduce the issue?

driver.Manage().Cookies.AddCookie();

Relevant log output

OpenQA.Selenium.WebDriverArgumentException: invalid argument: missing 'name',

You can't add a cookie that doesn't exist. You need at least a name and value.
https://www.selenium.dev/documentation/webdriver/interactions/cookies/?tab=csharp#add-cookie

@nvborisenko shouldn't this fail for not sending a cookie instance to the method?

[nvborisenko]

The issue is reproduced, thanks for the report.

It is related to Native AOT.

driver.Url = "https://google.com";

driver.Manage().Cookies.AddCookie(new Cookie("a", "b"));

Ah, we have logs! :)

Here we can see that AddCookie command serialized improperly.

[nvborisenko]

As a workaround you can mark your method, which invokes AddCookie method, with the following attribute:

[DynamicDependency(DynamicallyAccessedMemberTypes.All, typeof(Cookie))]

I see even more places in selenium code base where json serialization doesn't work properly with Native AOT.

Hoping #13097 will resolve it.

thank, it working,

[nvborisenko]

Removing it from 4.17 milestone. This is rare case, when we want to be friends with, but cannot do it in discoverable future. I would like to keep it as opened, hoping #13097 resolve it.

[nvborisenko]

Hi @NCLnclNCL, are you able to help us to test the preview version of selenium package which seems to be AOT compatible (excluding CDP)? We are looking for everybody who is interested in it. @katanakatana123 and you?

[nvborisenko]

It should be fixed by #14574

[nvborisenko]

Verified, will be available in v4.26
