I'm trying to set up a dev environment for my Nodejs project using Skaffold to handle k8s. I notice that sometime when there's an error (usually syntax error cause I'm using auto-save), the entire local server seem to stop working and the error message doesn't get displayed. Sometimes it can fix itself but most of the time I have to restart skaffold. I have no idea what's causing the issues since the error message can be different everytime: "unable to connect to pod ..." , "502 error", "skipping deploy due to sync error" ...

Here's my simple dockerfile for node:

FROM node:alpine

WORKDIR /app

COPY package.json .
RUN npm install
COPY . .

CMD ["npm", "start"]

Package.json

  "name": "auth",
