and in js file:

odoo.define('web.ajax',function(require){"use strict";var core=require('web.core');var utils=require('web.utils');var time=require('web.time');function genericJsonRpc(fct_name,params,fct){var data={jsonrpc:"2.0",method:fct_name,params:params,id:Math.floor(Math.random()*1000*1000*1000)};var xhr=fct(data);var result=xhr.pipe(function(result){core.bus.trigger('rpc:result',data,result);if(result.error!==undefined){if(result.error.data.arguments[0]!=="bus.Bus not available in test mode"){console.error("Server application error",JSON.stringify(result.error));}

I have tried to run on odoo runbot but there was also problem, the steps i made to sync it was :

1. on website https://console.developers.google.com/ i made everything like in instruction, i've got id and secret, add site to js auth and two records in URIs with /auth_oauth/signin and /google_account/authentication . 

2. Add in odoo settings id and secrets, downloaded configured oAuth2.

Everything went well, i clicked sync with google button i calendar, and showed premission from google, i clicked allow and got back to odoo website, on this step i have token etc. and i want to click second time and this problem appeared.

Can someone help me ?

Thanks.
