DocViewer requests twice.

[engadori]

Hi Cyntler.

When I using 'uri' props in 'DocViewer' component, It requests twice to my backend api.

here is my process. when I request my file to backend, It needs 'Authorization' headers. The 'Next js API' was simply settings that headers

When I tested except 'Nextjs API', same result ( requesting twice ).

what should i do? plz give me some feedbacks.

It makes a HEAD request followed by a GET. Could that be what you're seeing?

The first call might be a prefetch call followed by an actual API call.

By default prefetch use HEAD method call but can be overridden to make GET API call for prefetch as well.
