Build nextJS app issue - Cannot read properties of null (reading 'message')

[anteqkois]

Current Behavior

When i build locally app, usign nx run web:build all works fine. But when I build docker image anr run RUN npx nx run web:build a got a misleading error:

332.1 ƒ Middleware                             40.3 kB

------
failed to solve: process "/bin/sh -c npx nx run web:build ${BUILD_FLAG}" did not complete successfully: exit code: 1

So I see that NextJS app was built, but the error broke my image build

Expected Behavior

Here is my docker file:

FROM linkerry-base:base AS builder

ARG NODE_ENV

WORKDIR /app/builder

# comment this step now, project files alreaady exists
# COPY . .

RUN npx nx run web:build ${BUILD_FLAG}

This issue also occurs when u build docker image for my nestJS app

I had this issue when migrating to a newer version of NX (unsure if related) and found that force disabling the NX Daemon in my Dockerfile solved my issue: ENV NX_DAEMON=false

For all you folks who are searching the web for Cannot read properties of null (reading 'message') and pulling your hair out because your CI builds all of the sudden began failing:

The latest Gitlab update to Version 17 breaks NX's is-ci. I don't know why as the CI and GITLAB_CI variables are still provided FWIW, but it breaks 🤷

Adding ENV NX_DAEMON=false to your Dockerfile will fix it, thanks @Malagari !

EDIT: Looking at the latest changes to the is-ci package, it may be due to this change: packages/nx/src/utils/is-ci.ts
