},What happened?
When running tests that rely on the W3C WebDriver performActions API, WebdriverIO generates action sources with incrementing ids (action1, action2, …). This leads to invalid argument errors when multiple action types (keyboard, pointer, wheel) are used in the same session.
According to the W3C WebDriver spec, each input source id must:
Remain unique for the duration of the session
Always map to the same action type (key, pointer, wheel)
Currently, BaseAction in packages/webdriverio/src/utils/actions/base.ts generates ids like action1, action2, etc. This means the same id can be assigned first to a key input source and later reused for a pointer input source, which causes WebDriver servers (Chromedriver, Geckodriver, etc.) to reject the action request.
What is your expected behavior?
