Lasso errors with Failed to walk dependency

[jasonmlaster]

I am just learning node along with Marko and lasso, so it is very possible I've simply missed something core, but I've been attempting to make a test app which calls external URL to process data. I am getting errors which seem to suggest missing dependencies from included request module, but only when running it under a marko app with lasso.

Things I tried:

• Ran just the request portion of component.js in an example .js file which worked as expected. (Suggesting that request doesn't actually have issues?)
• Add the dependency reported in the error output. This just kept change the last failed dependency, but never fully worked as it ended with a 'crypto' requirement that was depreciated.

Does anyone see anything obvious I missed. I'm asking this in lasso since the first mention outside of a dependency requirement is related to walk dependency from lasso.

Found https://github.com/salesforce/tough-cookie/issues/125 which references the failure due to the included net use for isIP. Wondering if lasso is setting a similar environment that would trigger this failure. If so my issue doesn't seem to be related to lasso.

Closing this. I've done more looking into it and something is odd about included libraries. I had the same behavior with the included http/https libraries. No indication this is lasso.
