Studio login not working (Invalid client_id parameter value)

[harout]

I have a tutor open edx installation on AWS
Tutor version : version 15.3.0
Open edx version: Olive
I have created superuser and signed in to the LMS successfully , when tried to sign in to the Studio I have been redirected to the LMS with this error message:

## Error: invalid_request

Invalid client_id parameter value.

The redirection link :

<lms_domain_name>/oauth2/authorize?client_id=cms-sso&redirect_uri=https%3A%2F%2F<cms_domain_name>%2Fcomplete%2Fedx-oauth2%2F%3Fredirect_state%3D8n7QdQelURDoGvkRw2r6KK17zzZgEglX&state=8n7QdQelURDoGvkRw2r6KK17zzZgEglX&response_type=code&scope=user_id+profile+email

I have read some of the forum topics related to the studio login but didn’t find anything, anyone faced this or solved this issue ?

When you go to https://<your lms>/admin/oauth2_provider/application/ can you see an application called “cms-sso”?

I can see only:

• android

• Login Service for JWT Cookies

Did you run tutor local launch to the end? Did it succeed? It should have.

I have re-ran the tutor local launch and it worked.

the “cms-sso” has been added to the oauth2_provider applications and the login to studio worked.

Thanks
