  • This code will parse and evaluate if I put it into a file called main.mjs and then run node main.mjs.

Am facing the below issue in Docker, i tried ignoring node_modules in my .dockerignore as mentioned here

Error: /lowcode/node_modules/isolated-vm/out/isolated_vm.node: invalid ELF header

code: 'ERR_DLOPEN_FAILED'

If my file has below snippet, am seeing the above error during docker up, if i remove that its running fine. My node version is 18 and even tried v20.

const ivm = require("isolated-vm");

You need to run npm install from inside the container, not outside. And ignore node_modules.

COPY package.json package.json
COPY package-lock.json package-lock.json
RUN npm install

Got that, was trying the same earlier and now found the root cause, volume mount is causing the issue, resolved. Thanks for the prompt response! Appreciated.
