Build fails on 6.0.0 - alpha 6

🌵 Needle Engine

Hi,

Taking production build using npm run build or npm run build:production fails on latest version with following error

Build pipeline task did not succeed.
error during build:
Error: [needle-buildpipeline] - Build pipeline failed. Please check the logs above for more information.

code: ‘PLUGIN_ERROR’,
plugin: ‘needle:buildpipeline’,
hook: ‘closeBundle’
}

Reproducible in the sample scenes. This is from needle sample scene Splines.

Thanks

The needle:buildpipeline error at closeBundle is a generic wrapper — the real cause is printed in the lines above that stack trace (the plugin logs the underlying failure first).

Most likely culprits on 6.0.0-alpha.6:

  1. Node.js too old — 6.0-alpha uses Vite 8 / rolldown (visible in your stack trace), which requires Node 20.19+ or 22.12+. Run node -v.
  2. Missing toktx — the production pipeline runs texture compression; toktx must be installed and in PATH (see Optimization docs).
  3. Compression/licensing — build-time compression is license-gated; make sure you’re signed in (npx needle-cloud login).

Next steps:

  • Paste the log output from just above the stack trace (the real error).
  • Check ls -t node_modules/.needle/logs/ for the generated server logs.
  • As a quick workaround, disable compression (Development Build toggle / build without --production) to confirm the pipeline itself runs.

If you can share those lines, I (or Needle Cloud AI with your project connected) can pinpoint it — this smells like an alpha-specific pipeline regression, so the exact log matters.

For project-specific help, ask Needle Cloud AI.

Hi, as AI said this isn’t the full error unfortunately. Have you checked the full log? The AI also pointed you to the location of possibly more logs.

Hello @Ashokkumar_KR which Unity and Needle Engine version are you currently using and how did you trigger the build? Somehow the plugin did use the fallback version which is not available yet (normally Unity provides the exact version - since we’re in alpha the stable version is not published yet)

Logs also show: Successfully received "BASIC" license < Do you see a Pro license in Unity?

Note that if you haven’t tried you can use Needle Cloud AI as well and ask if about the issue - it can directly read all the logs in your project and potentially help with your problem directly since it has more context. To try just go on cloud.needle.tools als use the Ask AI button when logged in.

I’m on the latest 6.0.0 alpha 6 with unity 2022.3.55.
Even for standalone web projects, the build is failing.

At the start of the build, I see " Successfully received pro license " printed on the console; towards the end of the build, before it fails, I see “Successfully received BASIC license” this as well.

Sharing the error log of this as well.

Are you triggering the build from Unity or via the commandline?

From command line.
It succeeded for the sample project (Splines) when i triggered it from unity but failed through command line.

Hi, thanks that confirms it.

During alpha the stable build pipeline is not released (version 4) which is used as a fallback version in the plugin and then fails.

Until we’re closer to a stable version you can use this instead via e.g. windows commandline:

set "NEEDLE_BUILD_PIPELINE_VERSION=4.0.0-next.1786637167.chunky-prickly-pear.17c5bfe" && npm run build

This sets a environment variable - when you build from Unity the version is passed along from the Unity package, that’s why it works. Just keep in mind that during alpha this version might change when you update (the Needle Engine for Unity package contains that exact version). It should unblock you for now.
