I have done the following:

1. Downgrade to oracledb version 5.5.0
2. Run the script (Thick mode):

import oracledb from 'oracledb';
oracledb.initOracleClient();   

Iit produces the following:

Error: DPI-1047: Cannot locate a 64-bit Oracle Client library: 
"libaio.so.1: cannot open shared object file: No such file or directory".

3. Because Ubuntu 24.04 has replaced the "libaio1" package with "libaio1t64", to resolve this, I create a symlink from "libaio.so.1t64" to "libaio.so.1" using the command:

 sudo ln -s /usr/lib/x86_64-linux-gnu/libaio.so.1t64 /usr/lib/x86_64-linux-gnu/libaio.so.1

4. Upgrade to oracledb version 6.8.0.
5. Run again the scripts without any problem.

@alberthastings Thanks for posting the solution and closing this.

It seems to be an issue with Ubuntu OS not supporting a required library for Oracle Instant Client 12c.
I suggest you move to the latest Oracle Instant Client version.
