error message "Error: "none" is not a supported platform. Choose either "ios" or "android"." every 10seconds

since upgrading to expo 48, I get the message above every 10 seconds when I start expo

I have the same issue, still looking for a fix

Hi @acheuk and @gdanov-finstep

I have not seen that behaviour before.

Maybe create a new app for testing purposes.

Does the new app do the same thing?

If not, compare app.json and the other config files between the real app and the test app to see if one of the differences might be causing the problem.

I tracked it down to Flipper. Happens only while it’s running. Coincides with the point in time it’s integration stopped working properly.
