Could not find package.json up from undefined

I'm now getting a new issue using this in lambda, seemingly caused by pkginfo introduced in this PR - https://github.com/what3words/w3w-node-wrapper/pull/31 because no package.json was deployed with our lambda (it's not required if there are zero dependencies, as they've all been inlined). If I added a package.json I then got the following:

"TypeError [ERR_INVALID_ARG_TYPE]: The \"path\" argument must be of type string. Received undefined",
"    at validateString (internal/validators.js:120:11)",
"    at Object.dirname (path.js:1128:5)",

but for reference to others, I've worked around this by excluding what3words from esbuild bundling entirely by CDK, so it's kept as a separate dependency:


const someLambda = new NodejsFunction(this, 'someLambda', {
      runtime: lambda.Runtime.NODEJS_12_X,
      entry: path.join(__dirname, `/../resources/lambda/s3-trigger/index.ts`),
      bundling: {
        minify: false,
        preCompilation: true,
        externalModules: [
          'aws-sdk'
        ],
        // what3words has been problematic so easier to keep seperate
        nodeModules: ['@what3words/api'],
      }
    });
