My flow was working without an error before i updated pad to the latest version.
I was passing a url in "Launch new chrome" action, like this
"https://xxxxxx.com/custom/service/webapi/rest.php?input_type=JSON&response_type=JSON&method=login&rest_data={"user_auth":{"user_name":"xxxx","password":"xxxx"}}"
Now, when the chrome window opens up, the url does not have any double quote (") characters and my url is not working.
