I posted a longer thread over on discourse regarding this but am cross posting shorter version here in case slack is preferred for help. I have a lambda function that runs fine during local live development but fails when deployed to AWS. I'm using the mailchimp node module which is a client to their web services. It's not an es module but i'm importing it like this:

import mailchimp from "@mailchimp/mailchimp_marketing";

When I run the lambda on AWS I get the following error:

"errorType": "TypeError",
    "errorMessage": "Cannot set property 'setConfig' of undefined",
    "stack": [
        "TypeError: Cannot set property 'setConfig' of undefined",
        "    at /var/task/src/test.js:7:245570",
        "    at /var/task/src/test.js:1:249",
        "    at /var/task/src/test.js:7:249760",
        "    at /var/task/src/test.js:1:249",
        "    at Object.<anonymous> (/var/task/src/test.js:7:249825)",
        "    at Module._compile (internal/modules/cjs/loader.js:1085:14)",
        "    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1114:10)",
        "    at Module.load (internal/modules/cjs/loader.js:950:32)",
        "    at Function.Module._load (internal/modules/cjs/loader.js:790:12)",
        "    at Module.require (internal/modules/cjs/loader.js:974:19)"
    ]

The line that fails is not in my own function code, but the included mailchimp source that's transpiled into the lambda at the top. Other node modules I'm using work fine. Is this an issue with the mailchimp module or some bug in the transpile? Again, it all works fine during live development. I'm running version

0.66.3

Thanks for any help!

That’d be the first thing I’d try, prevents the bundler from doing anything with it

How do I get it to pull from the node_modules in the project root? SST is complaining there's not a package.json in my src/ directory. Thanks!

Strange, the node_modules folder should be at the root, same level as the sst.json

It is, and I do have the module installed there. It's in the root package.json:

"dependencies": {
    "@mailchimp/mailchimp_marketing": "^3.0.74",
    "@serverless-stack/cli": "0.66.3",
    "@serverless-stack/resources": "0.66.3",
    "aws-cdk-lib": "2.7.0",
    "email-validator": "^2.0.4"
  }

But when I build, SST says it's looking for a package.json in my src folder:

Error: Cannot find a "package.json" in the function's srcPath: /Users/chris/Documents/xsol-app/src

I've been grappling with this exact issue for longer than I'd like to admit and this helped! Thanks
