Docker alpine dependency?

Das Issue nennt Cloud9, Docker, esbuild und den Befehl cdk deploy, aber keine Quelldatei oder keinen Test des Projekts. Beginne damit, cdk deploy auf einer frischen Cloud9-Instanz zu reproduzieren und den Bundling-Fehler zu untersuchen; abgeschlossen ist es, wenn das Asset erfolgreich gebündelt wird und das Deployment ohne den Fehler wegen des fehlenden esbuild abgeschlossen wird.

Hello,
Thanks so much for putting together this sample. I am trying to deploy on a fresh Cloud9 instance, and cdk deploy is bombing on the esbuild step. Suggestions for getting over this hurdle? Stack is below.

Step 13/13 : CMD [ "esbuild" ]
