SwitchToFrame ERROR with chromedriver 75 and Nightwatch 0.9.21

[jiri-skrivanek]

With upgrade to chrome 75.0.3770.100 and chromedriver 75.0.3770.90 we started to get an error:

RESPONSE SwitchToFrame ERROR invalid argument: 'id' can not be string

I noticed workaround in bug #2118. If I set w3c=false it works. Can it be fixed in Nightwatch 0.9 or what is the permanent solution? Thanks.

chromedriver >= 75 works in w3c-mode by default, but Nightwatch 0.9.21 works with chromedriver in legacy JsonWire mode by default. So, they don't understand each other.

For chromedriver 75 use w3c:false.

For chromedriver >= 76 you can also use webdriver: { use_legacy_jsonwire: false }
(#2118: ... chromedriver 76.0.3809.25 and beyond will accept Is Displayed command in both W3C and OSS modes)
