I'm trying to add leveldb as a dependency for a lambda and running into the following error when handling a request in live dev mode:

No native build was found for platform=darwin arch=x64 runtime=node abi=72 uv=1 libc=glibc node=12.22.6

at Function.load.path (.../node_modules/node-gyp-build/index.js:59:9) ...

There is a binary dependency,

leveldown

which I've tried adding to bundle.nodeModules without success. I've confirmed that locally the darwin-x64 binary is present (in node_modules). I've also confirmed that the issue does not occur when deploying to the lambda to aws. Any suggestions?

Hey @Kelly Davis, can I see what your

package.json

looks like and how you are defining the function?

const fun = new sst.Function(this, 'router', {
      runtime: 'nodejs14.x',
      handler: '../js/mylambda/src/index.koaHandler',
      bundle: {
        externalModules: ['aws-sdk'],
        nodeModules: ['leveldown'],
      },
      timeout: 300,
      environment: {
        STAGE: stage,
        BASE_HOSTNAME: process.env.BASE_HOSTNAME,
      },
      vpc,
      vpcSubnets: {
        subnets: [subnet1, subnet2]
      },
    })
