Upside of using Support for Firebase Cloud Messaging (FCM) over expo?

Hi,
I went through the guide and fail on the upload api-token step, what kind of failures do you think I can expect here, the error message is just too generic:

>exp push:android:upload --api-key MY_TOKEN_HERE
13:54:24 [exp] Reading project configuration...
13:54:24 [exp] Logging in...
13:54:24 [exp] Setting API key on Expo's servers...
13:54:25 [exp] An unknown error occurred.

anyway I can see the logs?

sorry that I asked this on other thread, but it a bit urgent, and I assumed you are the go to guy for these issues :man_firefighter:

Thanks,
Oren.
