SOLVED:

Generally you should specify paths relative to SST.json

--- This might seem obvious but it isn’t to me so if someone knows, I’d appreciate it. I have the following directory structure:

src/
  lambda-handler/
    rewiter.js
stacks/
  SiteStatck.js
  index.js
sst.json

Inside

StaticSite

, I’d like to attach an edge lambda function. That looks vaguely like this:

const originRewriteHandler = new experimental.EdgeFunction(
      this,
      "OriginRewriteFunc",
      {
        runtime: lambda.Runtime.NODEJS_14_X,
        handler: "src/lambda-handler/rewriter.main",
        // this path is wrong and I can't figure it out
        code: lambda.Code.fromAsset(path.join(__dirname, "lambda-handler")), <----------------------
      }
    );

Everywhere I go with different paths I end up in

.build

Generally you should specify paths relative to SST.json

I think what that means is that

code: lambda.Code.fromAsset(
          path.join(__dirname, "../../src/lambda-handler")
        ),

and my new error of

TypeError: origin.bind is not a function

is actually a success message!
