How to save and then load cookies in PhantomJS?

Question

Python

Until this beautiful evening, I saved cookies in this way:

with open("cookie/1.pkl", "wb") as cookiefile:
        pickle.dump(browser.get_cookies(), cookiefile)

and then loaded like this:

with open("cookie/1.pkl, "rb") as cookiefile:
            cookies = pickle.load(cookiefile)
            for cookie in cookies:
                browser.add_cookie(cookie)

Today I tried to crawl to PhantonJS and ran into the problem of saving and loading cookies.
Gives an error messageselenium.common.exceptions.InvalidCookieDomainException: Message: {"errorMessage":"Can only set Cookies for the current domain","request":{"headers":{"Accept":"application/json","Accept-Encoding ":"identity","Content-Length":"169","Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1:54294","User-Agent ":"selenium/3.141.0 (python mac)"},"httpVersion":"1.1","method":"POST","post":"{\"cookie\": {\"domain\": \"ex.ru\", \"httponly\": false, \"name\": \"viewport\", \"path\": \"/\", \"secure\": false, \" value\": \"768\"},\"sessionId\": \"3e5100e0-c44e-11e9-b7ad-81c50dc259c4\"}","url":"/cookie","urlParsed":{"anchor":"","query":"", "file":"cookie","directory":"/","path":"/cookie","relative":"/cookie","port":"","host":"","password ":"","user":"","userInfo":"","authority":"","protocol":"","source":"/cookie","queryKey":{}," chunks":["cookie"]},"urlOriginal":"/session/3e5100e0-c44e-11e9-b7ad-81c50dc259c4/cookie"}}"url":"/cookie","urlParsed":{"anchor":"","query":"","file":"cookie","directory":"/","path":"/ cookie","relative":"/cookie","port":"","host":"","password":"","user":"","userInfo":"","authority" :"","protocol":"","source":"/cookie","queryKey":{},"chunks":["cookie"]},"urlOriginal":"/session/3e5100e0-c44e- 11e9-b7ad-81c50dc259c4/cookie"}}"url":"/cookie","urlParsed":{"anchor":"","query":"","file":"cookie","directory":"/","path":"/ cookie","relative":"/cookie","port":"","host":"","password":"","user":"","userInfo":"","authority" :"","protocol":"","source":"/cookie","queryKey":{},"chunks":["cookie"]},"urlOriginal":"/session/3e5100e0-c44e- 11e9-b7ad-81c50dc259c4/cookie"}}directory":"/","path":"/cookie","relative":"/cookie","port":"","host":"","password":"","user": "","userInfo":"","authority":"","protocol":"","source":"/cookie","queryKey":{},"chunks":["cookie"]} ,"urlOriginal":"/session/3e5100e0-c44e-11e9-b7ad-81c50dc259c4/cookie"}}directory":"/","path":"/cookie","relative":"/cookie","port":"","host":"","password":"","user": "","userInfo":"","authority":"","protocol":"","source":"/cookie","queryKey":{},"chunks":["cookie"]} ,"urlOriginal":"/session/3e5100e0-c44e-11e9-b7ad-81c50dc259c4/cookie"}}"source":"/cookie","queryKey":{},"chunks":["cookie"]},"urlOriginal":"/session/3e5100e0-c44e-11e9-b7ad-81c50dc259c4/cookie"}}"source":"/cookie","queryKey":{},"chunks":["cookie"]},"urlOriginal":"/session/3e5100e0-c44e-11e9-b7ad-81c50dc259c4/cookie"}}
