Hi,

I have problem with finalizing this module, the problem is concerning step "Get Your Application Up and Running", points 3 and 4.
I am receiving error message: [Agent] ERROR: Not logged into Salesforce, so  I am following the instruction and clicking Agent URL, which should redirect me to the login page. 

Unfortunately I receive white screen with error message: error=invalid_client_id&error_description=client%20identifier%20invalid

Please let me know if had similiar problem and/or how I can solve this issue.

Best regards
Sylwester
