Error starting tunnel: XDLError: TypeError: Cannot read property 'toLowerCase' of undefined

#1

Hello, I am making an app with react native using expo. Some days ago, when I started it with the commando ‘exp start’, as I always do, it gave me an error:
"Error starting tunnel: XDLError: TypeError: Cannot read property ‘toLowerCase’ of undefined"
It was the first time. I think it’s because I have updated the expo CLI from the version 45.0.0 to 45.0.1
Can someone help me to sovle it?
Thanks for reading.
Alessandro.

I believe your account session may have gotten corrupted. Can you try exp logout && exp login and see if that resolves things?
