Fix Netlify cms failed to load entry api_error object object in with Gitlab

Hello all, I will share fixing error Netlify CMS with message "failed to load entry api_error object object". in my case is because netlify CMS don't have access permission to access gitlab repository. Gitlab repository required Access Token for request from Netlify CMS.

Solution:

Login in Netlify account
Open Site menu
Click your site
Entry to Identity
Scroll to bottom and and get menu Git Gateway
Edit Setting
Click Generate token and it will be redirect to Gitlab account and token will autofill when you have done in Gitlab
