Failure instrumenting specific code

Instrumentation failing on js files that have keywords "export" and/or "import".
Error: Line 1: Unexpected token

Trying to instrument a program and provide code coverage for selenium tests. Currently struggling with this.

same error with this code

const im = require('istanbul-middleware'),
im.hookLoader(currentpath); // cover all files except under node_modules

no error if you write

const im = require('istanbul-middleware'); // <== ``;`` here, not ``,``
im.hookLoader(currentpath); // cover all files except under node_modules

you can close

I'm not experiencing the issue during execution of the driver. Experiencing the issue during instrumentation.
So when i run :
istanbul instrument "path_to_code" --output "output_path" --embed-source-true

then only do I experience this issue.
I think it has to do with support for ES6 and typescript, because I've seen similar problems experienced by other users for ISTANBUL, however i cant be sure
