Hi,
I'm a super experienced REACT, NODE JS, FIREBASE and GCP developer.
Having used FIREBASE HOSTING very well, the issue with your hosting is simply because you need to upgrade to the BLAZE PLAN from your console or if you're already on the BLAZE PLAN, then it maybe telling you about your FREE monthly LIMIT after which standard charges will be applied.
Please reach out to me, so I can help troubleshoot any related issue.
If the above write-up had solved your problem, please do reach out, so you can give me a five star and a token to boost my career on here.
I look forward to hearing from you.
Best regards,
Michael Obademi,
Software Engineer.
