Web App 2018r4 libunwind.so.8

Hi everyone,
If I try to run my standalone web app on Debian server, I see "error while loading shared libraries: libunwind.so.8: cannot open shared object file: No such file or directory "., then (Unfortunately it is a shared hosting and therefore I cannot install this library in the canonical way.) manually I have download the libunwind.so.8 package from debian, unpack it and copy the libraries to the Libs folder of my standalone web application.
Now if I try to run the app it show another lib missing :
"error while loading shared libraries: liblzma.so.5: cannot open shared object file: No such file or directory "
I have done the same thinks for this library (download and copy in Libs) but doesn’t work, still show the error message.

What am I doing wrong ?

Anyone can help me ?
Thanks
