liblzma.so.5 missing in docker image / adding solves AWS lambda issue

[georg-wind]

Problem:
I used this excellent script to generate binaries for use in AWS lambda (python3.11 runtime). Calling pdfinfo, it raised this exception:
"liblzma.so.5: cannot open shared object file: No such file or directory". The .so should probably be shipped with the AWS runtime but apparently whatever we got wasn't working for us.

Fix:
I generated the binaries again, but accessed the running docker container and copying liblzma.so.5 from its lib64/... path (got exact path from ldd pdfinfo) to the poppler_binaries (adding it) folder before proceeding as usual (copying to host, zipping, ..).

I assume it could be added to the standard image.
