AWS lambda deployment for skottie, embedded fonts not rendering

[ashishpadave]

I am developing a AWS lambda function to extract png frames from a lottie animation. The problem is that the fonts aren't rendering. Fonts are embedded inside lottie with base64 encoding.
I tried using both SkiaSharp.NativeAssets.Linux.NoDependencies and SkiaSharp.NativeAssets.Linux package, but it failed with errors of missing. The solution runs perfectly on the Windows 10 Development Environment.

Unable to load shared library 'libSkiaSharp' or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable: libfontconfig.so.1: cannot open shared object file: No such file or directory /var/lang/bin/shared/Microsoft.NETCore.App/8.0.10/libSkiaSharp.so: cannot open shared object file: No such file or directory /var/task/liblibSkiaSharp.so: cannot open shared object file: No such file or directory /var/lang/bin/shared/Microsoft.NETCore.App/8.0.10/liblibSkiaSharp.so: cannot open shared object file: No such file or directory /var/task/libSkiaSharp: cannot open shared object file: No such file or directory /var/lang/bin/shared/Microsoft.NETCore.App/8.0.10/libSkiaSharp: cannot open shared object file: No such file or directory /var/task/liblibSkiaSharp: cannot open shared object file: No such file or directory /var/lang/bin/shared/Microsoft.NETCore.App/8.0.10/liblibSkiaSharp: cannot open shared object file: No such file or directory

Development environment: Visual Studio 2022 on Windows 10. Using the AWS Toolkit extention for deploying to AWS.

Any help is appreciated.
Thanks in advance.

Created a Lambda Layer with the fontconfig library taken from a Amazon2 WSL instance, added the fonts and the fonts.conf to the the layer.
Set the environment variables to

FONTCONFIG_PATH  /opt/fonts   -- contains the fonts and the fonts.conf
LD_LIBRARY_PATH  /opt/lib -- contains the fontconfig, png and other libraries.

Fonts.conf contents:

<fontconfig>
<dir>/opt/fonts/</dir>
<cachedir>/tmp/fonts-cache/</cachedir>
<config></config>
</fontconfig>

Note: The Zip file for the layer should have fonts and lib folders only not the /opt folder, since lambda mounts the layer on /opt.
