I have a signup page that uses create-react-app on the front end and firebase functions/express on the back end.
Signup works as expected from localhost. But when deployed to Netlify, when I try to signup, there is a 404 POST error in console with my netlify url. I would expect it to be my firebase api url, not my netlify url.
So I am wondering if my proxy I have in my package.json file is not being handled by netlify. I tried adding the firebase api url to my _redirects file but that did not work either.
