Cloudflare for SAAS: SSL stuck on pending

I am using Cloudflare for SAAS and there is a domain that has it’s CNAME record set up correctly. But the SSL is stuck on pending. The API has this response:

"code": 1011,     
"message": "Plan level does not allow custom certificates with type " 

I’m not sure what type means or what is different about this domain.

did you get any solution yet?
