Unable to deploy app successfully using the Zip method


I’ve tried several ways from the docs but nothing works. I settled with the ZIP file method but that has issues across platforms too
I get this error when I try from the browser https://answers.netlify.com/t/the-access-control-allow-origin-header-contains-multiple-values-but-only-one-is-allowed-when-trying-to-deploy-zip-file-through-netlify-api-endpoint/78674
And I get an error saying “Blob is not supported” when I tried using firebase functions

Can anyone help please.

Hi @Mankind,

Thanks for reaching out!

To clarify, are you using the Drag and Drop feature or another method? Could you provide us the Netlify site name that you’re trying to deploy to?

I’m using the Netlify API api.netlify.com/api/v1/sites

Tried multiple sites already but here’s one: https://teal-sundae-517540.netlify.app

As mentioned in the other thread, you cannot upload to Netlify API from a browser due to browsers’ (security) limitations.

Regarding Firebase, is that error coming from Netlify API or Firebase?
