Inkscape Pattern along path generate repeated outline and not fill

Question

New to Inkscape,

I want to make a "binary film reel strip", so I found a film slide SVG in publicdomainvectors, and want it to repeat on a path.

1. I drag the SVG on the canvas
2. select and copy the slide
3. draw a path and add Path Effect : "Pattern along path"
4. I get only the outline, and not the content
   (I could get the content before, but I don't know exactly what I did to achieve that.
   furthermore, it did not ever repeat the 101010101 text in the slide) [

I tried converting everything to paths, also to pattern, with and without grouping.

please help!
how can I repeat a pattern in it's whole, and not only it's outline?

Edit: Thanks to @BillyKer answer, I got a bit further, but still not what i try to achieve (and not as Billy's example shows)

1. Ungrouped everything
2. convert to path
3. ungroup again
4. convert to path again
5. path>combine
6. copy
7. apply as repeated pattern

This is what I got:
details are shown now, but as outline of the detail :\

any idea what I'm doing wrong?

Answer 1

You need to convert the graphic to a combined path first.

1. Ungroup it until there are no groups left, select all of it and click Path > Combine.

2. Now, copy it

3. Add the pattern along a path effect, then in the path effects, set to "Repeated".
