Node 12 breaks oracledb in rule

Hello,

In a rule I get roles for a user from a sql query in an oracle database.

My node version is deprecated (Node 8), i have the warning raised by auth0 console but when I tried to switch to Node 12 the rule is failing with

Error: DPI-1047: Cannot locate a 64-bit Oracle Client library: “libclntsh.so: cannot open shared object file: No such file or directory”. See https://oracle.github.io/odpi/doc/installation.html#linux for help Node-oracledb installation instructions: https://oracle.github.io/node-oracledb/INSTALL.html You must have 64-bit Oracle client libraries in LD_LIBRARY_PATH, or configured with ldconfig. If you do not have Oracle Database on this computer, then install the Instant Client Basic or Basic Light package from http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

Rule code is :

           var oracledb = require('oracledb');
    		oracledb.outFormat = oracledb.OBJECT;

    		oracledb.getConnection({
    			user: 'xxxx',
    			password: 'xxxx',
    			connectString: "xxxxxxx" /
    		}

What can I do ?
thanks
