Any reason you are using such an old Node version (7.x)?

Upgrading to 8.6 will fix your issue.

I ask because we are considering bumping the Node requirement.

[maciekstosio]

Yes, it seems to work. I've seen 7.6 requirement in docs and i thought it will be enough. I have another issue, but I'm not sure if it's right place to ask.
My apps works that I have login page at the beginning, and after logging in there is screen that indicate data loading (downloading data in) and then it goes to dashboard. I've put id on main view of this loading screen and tried to check weather it shows after successful log in, but it doesn't detect it. Downloading data takes ~30sec so I'm wondering why it doesn't "see" it. Can it be caused by loading data?

[LeoNatan]

We synchronize on network, so yes, probably.

[LeoNatan]

@rotemmiz Let's bump the Node requirement.

[noomorph]

I think it's perfectly valid to close this issue as the 62da778 has been merged already.

I'm seeing same issue with Node v8.2.1 and Detox 8.0.0
Any suggestions what to do with this?

[noomorph]

Node v8.2.1

That's the problem. Come on, update to the normal Node v8.11.3 LTS.

The minimal requirement is: 8.3.0 See: 62da778#diff-d14d4a53aa4b327c46010adaa7ce8538R56
