You may be using certain features that require a Blaze plan.
If that is the case then there is no option except switching to the Blaze Plan.
Firebase Cloud Functions now require your project to be on the blaze plan. So you won't be able to deploy them unless you upgrade the plan. However, you can just deploy your site on Firebase hosting using the following command.
firebase deploy --only hosting
Use firebase deploy --help, for more info.
