Merge request description

This was one of the main gotchas for the Python 3.12 runtime upgrade but I forgot about it 😞

From developmentseed/titiler#1108:

I think it is a brittle solution but it might work for you too. The problem is that the execution environment is subtly different from the build environment as @vincentsarago suggested earlier. In this case the build environment (Lambda Python 3.12 image) has libexpat.so.1 available in the LD_LIBRARY_PATH which includes /usr/lib64 but the execution environment does not. The contents of the /asset directory which get zipped up to create the code package for the Lambda gets added to LD_LIBRARY_PATH so I think that's why it works. I hope that helps!

resolves #181
