git refuses to patch with the error "unrecognised input"

Question

On Windows 10...
(I am using powershell - if that makes a difference)

Creating a patch with:

git diff --no-prefix --no-color > bootstrap.patch

Creates a file like this:

diff --git Panda.Service/node_modules/bootstrap-sass/assets/javascripts/bootstrap.js Panda.Service/node_modules/bootstrap-sass/assets/javascripts/bootstrap.js
index 8a2e99a..ac84c8c 100644

       $next.addClass(type)

The relative paths are correct for the current directory.

Attempting to apply the patch...

git apply --unsafe-paths .\bootstrap.patch

Gives the following error:

error: unrecognized input
