我想使用Rselenum点击键盘的右键。但不幸的是，我得到这个错误。

x <- driver$findElement("xpath", "/html/body/c-wiz[2]/div/c-wiz/div[1]/div[1]/div[1]/c-wiz/div/div/div[1]/div/div[2]/div[1]/div/div[2]/div[3]/div/div[1]/section/div[2]/div/div[2]/div/div[2]/input")
x$sendKeysToElement(list(key='right'))

Selenium message:class com.google.common.collect.Maps$TransformedEntriesMap cannot be cast to class java.lang.CharSequence (com.google.common.collect.Maps$TransformedEntriesMap is in unnamed module of loader 'app'; java.lang.CharSequence is in module java.base of loader 'bootstrap')

我希望点击键盘的右键。
