Twig Extension undefined index notice

[mattsches]

The ReactPHP website displays a PHP notice with its stack trace in the activity box on the lower right (see attached screenshot).

This happens because the $participation array does not contain the index all. Might have sth. to do with connectivity issues to Travis, or maybe they changed something on their side?

Thanks for reporting, that alread happened a few times. The reason is probably a failed call of the github API.

We should probably fail the build in this case.

We should probably fail the build in this case.

👍 on failing the build in that case.
