Was it a mistake using my current manager as a reference?

I’ve been at this job going on two months, and it was a 3 month contract job. My manger and her boss are saying they need to get the ceos approval to get approval for a reference. This contract job offers no benefits, has me onsite 5 days a week, when the person training me is fully remote. Didn’t list in the job description, that it is contract, or the pay( which is now a law in my state)
