How to fix 'Redirects to data: URL are allowed only when mode is "no-cors"'? #32

Open holyjak opened 5 years ago

Hello,

this is not a bug but perhaps a gap that would be nice to fill in the docs as I suppose it is not an uncommon problem. When I use URL->File redirect, it is applied but the XHR call fails with:

Fetch API cannot load . Redirects to data: URL are allowed only when mode is "no-cors".

Is it possible to fix e.g. by using R.O. to set some req/response headers? Thank you!!!

PS: Perhaps it is related to https://github.com/whatwg/fetch/issues/111 and/or https://bugs.chromium.org/p/chromium/issues/detail?id=521475 but I do not understand the problem well enough.

I used URL -> URL instead of URL -> File, and pointed the endpoint to https://www.mocky.io/ where I mocked the desired response body.
