sprockets sprocket-context cause test to fails only on CircleCI

Sprocket cause test to randomly fails on CircleCI

Expected behavior

I expected the test to pass grancefully

Actual behavior

My test randomly fails time to time on CircleCI (Sometime it pass but I have to rebuild for 4-5 time). And most of time it is occur in the one of request spec(same error but occur in different test file) The same test(Rspec) suite alway pass on local machine but randomly fails on Circleci and this is full trance:

Same here sprockets-4.0.0.beta7

Make sure you are using beta 7.

Can you give me an example app that reproduces the problem? Does the issue ever happen outside of CircleCI?

May 17 '18 13:05 schneems

@schneems Hi, yeah, it's beta7. For now i have large app (large AA stack + little frontend UI). Rail 5.1.6, Ruby 2.5.1 Maybe i can debug it from CLI? To detect the problem source.

May 17 '18 15:05 merqlove

@schneems Yeah, it is CircleCI only.

Same error in beta8 and during heroku deploy:

I think for now we need catch this error manually and rerun precompile.

My solution:

#!/usr/bin/env bash

message=$(rake assets:precompile 2>&1)

if [[ ${message} == *"undefined method \`[]' for nil:NilClass"* ]]; then
  ./precompile.sh
else
  echo ${message}
fi

exit 0
