Copilot for Security portal returns error 400

Question

After creating the capacity on the Azure portal, I navigate to https://securitycopilot.microsoft.com to finish the setup, but encountered the following error.

I am already have the owner RBAC to the subscription it exists in so permission shouldn't be an issue.
Appreciate any help and/or advice, thank you in advance.

Answer 1

The Security Administrator role must be active. Once it is all works

Answer 2

Ok, so the missing role is the Azure Security Administrator role and this was not active and kept getting these errors.

Answer 3

Why is it acceptable that this service generates a meaningless and misspelled error code and we're all stuck figuring it out? I got stuck on this yesterday and had to leave off working on it, and overnight it ate $140 because I'm still learning how to set it up and haven't gotten to how to turn it off.
