error with optimized lambda

[stevecrozz]

I get this error on a lambda function when it has been optimized by this plugin. Without the plugin, the function works. I'm using the 'test' button from within the AWS console to produce this error:

{
  "errorMessage": "Cannot find module './aes'",
  "errorType": "Error",
  "stackTrace": [
    "Function.Module._resolveFilename (module.js:338:15)",
    "Function.Module._load (module.js:280:25)",
    "Module.require (module.js:364:17)",
    "require (module.js:380:17)",
    "i (/var/task/ivr/selection/handler.js:1:497)",
    "/var/task/ivr/selection/handler.js:1:688",
    "/var/task/ivr/selection/handler.js:12:25267",
    "Array.map (native)",
    "Object.a.exports (/var/task/ivr/selection/handler.js:12:25244)",
    "o (/var/task/ivr/selection/handler.js:12:25428)"
  ]
}

I'm not sure how to debug this. But I can gather more info if you ask for something in particular.

I'm also getting an error when trying to use optimizer with my project.

{
  "errorMessage": "Cannot find module '\/usr\/lib\/node_modules\/aws-sdk\/apis\/metadata.json'",
  "errorType": "Error",
  "stackTrace": [
    "Function.Module._resolveFilename (module.js:338:15)",
    "Function.Module._load (module.js:280:25)",
    "Module.require (module.js:364:17)",
    "require (module.js:380:17)",
    "i (\/var\/task\/accounts\/register\/handler.js:1:497)",
    "\/var\/task\/accounts\/register\/handler.js:1:688",
    "n (\/var\/task\/accounts\/register\/handler.js:3:27116)",
    "Object.i [as services] (\/var\/task\/accounts\/register\/handler.js:3:27572)",
    "Object.<anonymous> (\/var\/task\/accounts\/register\/handler.js:6:1621)",
    "Object..\/api_loader (\/var\/task\/accounts\/register\/handler.js:6:1806)"
  ]
}

The endpoints that fail with this message do not rely directly on the aws-sdk. Instead they use dynamodb-doc. Disabling optimizer fixes the problem.

Excluding aws-sdk from the optimzer fixed my issue.

"custom":
{
    "optimize": 
    {
        "exclude": ["aws-sdk"]
    }
}

I'm getting a similar error when trying to import the "mongodb" module:

{"errorMessage":"Cannot find module './binary_parser'","errorType":"Error","stackTrace":["Function.Module._load (module.js:276:25)","Module.require (module.js:353:17)","require (internal/module.js:12:17)","o (/var/task/_serverless_handler.js:1:497)","/var/task/_serverless_handler.js:1:688","/var/task/_serverless_handler.js:1:16480","Array.forEach (native)","Object.a.10../bson (/var/task/_serverless_handler.js:1:16454)","o (/var/task/_serverless_handler.js:1:637)"]}

Unfortunately, excluding that module isn't an option for me. It's a needed dependency.

I'm having the same issue but when I exclude it and deploy there's no issue running import on the lambda O_o
