Help - getting error

[junglebells]

Here's the error from docker logs - please advise:

I just tried it locally and it ran fine. To be on the safe side, released a new Docker image. Can you see if this works now?

Thanks for looking into it - I am still getting this error:

$ docker run -it -e PORT=3000 --rm ghcr.io/tomayac/local-reverse-geocoder

I tried this with fresh install of Debian 12 and Ubuntu Server 22.04 - same error on both. Could there be a package missing?

@yjwong, as the original author of the Docker file, do you have an idea why this error happens in Docker contexts, but not when run locally?

[yjwong]

I suspect it might be the Node.js version that's used in the Dockerfile. Looking at the stack trace, the error happens on the import(), which is part of ES modules.

The Dockerfile uses Node.js v10 - rather old by now, and doesn't have dynamic imports enabled by default. I think this could be solved by using a newer version of Node.js as the base image - something newer than the "engines" declared in package.json.

I was able to fix this issue on my local machine by making the following changes to Dockerfile:

Line 1 changed to "FROM node:current-alpine" Line 5 changed to "ADD package.json package-lock.json postinstall.js /app/

@tomayac you may need to build the docker image after these changes.

Hope this helps. Thanks for a wonderful program.
