I'm trying to build some lambda's in node.js and I am using TypeORM with MySql. I have installed all required node modules but when I deploy lambda (via serverless) and test it, I get errors as follows. Using gulp to build and package .zip.
Log output from test lambda:

My research has led me to believe that it won't package correctly because its a native module. But i'm not sure. If so is there anyway to get native node modules to work with lambda's?? Any help would be much appreciated, thanks.

Gulp file calls a function from aws-lambda-typescript module that has numerous gulp tasks.
const gulp = require('gulp');
const awsLambdaTypescript = require('aws-lambda-typescript');
awsLambdaTypescript.registerBuildGulpTasks(gulp, __dirname);
Gulp packages .zip in a dist folder and then i copy to deploy>dev and then serverless deploy.
Thanks for your help!
Most likely something is wrong with your packaging process. I'd check the following items:
package.json
if mysql
is there. .serverless
directory to see if it includes your node_modules.
