Error: Cloud Functions deployment requires the pay-as-you-go (Blaze) billing plan. To upgrade your project, visit the following URL:

https://console.firebase.google.com/project/wissal-4736a/usage/details

For additional information about this requirement, see Firebase FAQs:

As the error message says, deploying Cloud Functions to your Firebase project requires that the project is on the pay-as-you-go plan. This doesn't necessarily mean you have to pay for it though, as the plan comes with a free tier. From the Firebase pricing page:

On the Blaze plan, Cloud Functions provides a perpetual free tier. The first 2,000,000 invocations, 400,000 GB-sec, 200,000 CPU-sec, and 5 GB of Internet egress traffic is provided for free each month. You are only charged on usage past this free allotment.

An alternative is to switch to using the Node.js 8 runtime, which doesn't yet require the account to be on a billing plan.

For more on this and how billing around Cloud Functions works in Firebase, see the FAQs on Cloud Functions runtime support and Cloud Functions pricing.
