Azure Pipelines job stuck building iOS version of React Native app

Question

I'm trying to build an iOS version of a React Native app using Azure Pipelines. I'm running the build using fastlane's action build_ios_app .

It works on my local machine perfectly fine, but it gets stuck on Azure with the following output:

[08:32:21]: ‌▸‌ ‌Compiling‌ LaunchScreen.xib‌
[08:32:25]: ‌▸‌ ‌Processing‌ Info.plist‌
[08:32:25]: ‌▸‌ ‌Running script‌: Bundle React Native code and images
‌[08:32:32]: ▸ ‌the transform cache was reset.‌

This is usually the step at which the packager is opened in a new terminal window.

On my local machine the output looks a little bit different at this step:

[11:38:15]: ▸ Processing Info.plist
[11:38:15]: ▸ Running script 'Bundle React Native code and images'
[11:38:15]: ▸ Touching Demo.app (in target: Demo)
[11:38:16]: ▸ Archive Succeeded

There is no ‌the transform cache was reset.‌ which indicates node is running out of memory on the Azure at some point?

• Bundling the app manually (via react-native bundle ... ) works fine though.

Update: Increasing the memory available for nodejs tasks (setting --max-old-space-size=8096 in the NODE_OPTIONS environment variable) makes the job fail (at least) with the following error message:

Any ideas how to solve this?

Answer 1

I ran into the same issue on my local machine, the solution was to update to the latest version of node js .

I guess your CI environment should be self contained, so version conflicts should not be a problem. But you maybe updated fastlane to a version incompatible with the node on your Azure server without realizing.
