Answer 1

This error message...

selenium.common.exceptions.InvalidArgumentException: Message: invalid argument
from invalid argument: 'value' must be a single Unicode code point

...implies that there was a compatibility issue while converting a non w3c command to w3c standard command.

As per the discussion in ActionChains perform returns exception 'value' must be a single unicode point this issue was observed with appium Version 1.11.1 when used along with ChromeDriver v2.45 setting the standards mode with:

goog:chromeOptions.w3c:true

Excert from release notes:

Resolved issue 2536: Make standards mode (goog:chromeOptions.w3c:true) the default [Pri-2]

---

Solution

An immediate solution would be to:

• Update ChromeDriver to current ChromeDriver v78.0 level.
• Update Chrome to current Chrome Version 78.0 level. (as per ChromeDriver v78.0.3904.105 release notes)

tl; dr

A couple of relevant discussions are as follows:

• perform() action chain - Getting exception
• ActionsChains key_action.pause causes "exception 'value' must be a single unicode point" in Appium Webview or Chromium
