Getting error "Unable to find a matching set of capabilities" when I try to launch safari browser on iPhone.

まず、issue に示されている Robot Framework の capabilities と Python binding の例を比較し、その後 Selenium Grid の session と matching-factory のログを確認します。報告されている remote URL を通じて iOS Safari の session を起動できる、再現可能な capability または設定の変更を特定できれば完了です。

For issues

We have recently started automating iPhone safari with robot framework selenium. Sometimes we get "Unable to find a matching set of capabilities" when we try to run iPhone safari. I searched online but could not find any issue like this. I feel there is some capabilities I am missing but similar capabilities is working when I used python language binding. Please help.

Steps to reproduce the issue

${capabilities}= Evaluate sys.modules['selenium.webdriver'].DesiredCapabilities.SAFARI sys, selenium.webdriver

Set To Dictionary ${capabilities} platformName=ios
Set to Dictionary ${capabilities} browserName=safari
Log To Console ${capabilities}

Open Browser url=https://www.google.com desired_capabilities=${capabilities} remote_url=http://localhost:4449/wd/hub

Expected behavior and actual behavior

When I try to run open browser for safari iphone no matter what I do I am not able to launch the browser.

I can run the similar code when I use python binding with same capabilities.

`
from selenium import webdriver

caps = {'browserName': 'safari', 'platformName': 'ios'}
driver = webdriver.Remote('http://localhost:4449/wd/hub', desired_capabilities=caps)
driver.get('http://www.google.com')
`

Environment

Browser: iOS Version 14.6
Browser driver: Safari 15.5 (17613.2.7.1.8)
Operating System: Mac
