Why, when saving SVG in figma, for some icons, it replaces stroke with fill and how to solve it?

Question

SVG

There is an icon, you can see from the screenshot that it is made of lines with a 2 pixel stroke of blue color, there is no fill.

But when I export it as svg, Figma for some reason changes the stroke to fill and outputs this:

<svg width="22" height="22" viewBox="0 0 22 22" fill="none" xmlns="http://www.w3.org/2000/svg">

</svg>

It may not matter to someone, I understand, but this is important to me and I want to understand why she does this and how to avoid it?

Answer 1

Alternatively, there are plugins for exporting svg with code cleaning. Try to use them, maybe they export correctly
