Undefined type on handling NetInfo event

[thangenius]

My app using ReactNative 0.47 and encounter the following error on importing deviceLog:

"Cannot read property 'toUpperCase' of undefined'
at line 69 of debug-service.js

This happens because connectionInfo.type is undefined. I've workarounded by checking !type before the check of type === 'none'
if (!type || type === "none") {...}
