Googling the error Error: Dynamic require of "buffer" is not supported indicates there ios an issue with a dependency using a CommonJS module import instead of an ESM import. One suggestion was to pass an argument to esbuild indicating the buffer module is external. This works because buffer is included in the Lambda runtime environment.

Nope. Still fails. this time for require of node:http.

More scouring to do.

I feel pretty confident that at one time the code worked fine and today started failing. I see no changes at all.

Is this a Lambda runtime issue? Will check if failure persists later.
