obj file doesn't show up in apk version

[hhj0988a]

Hi, this project might be stopped but I need help.
The 3D model show up normally after I create assets folder and copy my obj file to it in develope mode.
But after eas build (expo - apk) ,it does not show up.
I think eas does not include assets folder that I made.

So I tried to save the file using file system library.
But it look like directory path never work.

Is there an any way to load .obj file from file-system not in assets folder?
My application should be used in internal network system (no internet) so I can't use uri.

I did it by using plugin to copy file. But now I have another issue. I made custom 3d model. But it is not showing and got error "Couldn't read file from InputStream". But my file work very well with online 3d viewer (https://3dviewer.net/) Is there a limit size for .obj file ??
