Wp-calypso: Signup: Selecting "Online Store" results in a blank screen

[jancavan]

Steps to reproduce

1. Starting at URL: https://wordpress.com/start/
2. Pick the "Online Store" segment
3. Notice how a blank screen is being displayed instead of the Domain Search page

Note: This happened when I was in an Incognito window.

What I expected

To be taken to the next step which is Domain Search

What happened instead

I was shown a blank screen

Edit: These were the errors captured by @jblz and @creativecoder:

Browser / OS version

Google Chrome Version 75.0.3770.142
MacOS Mojave 10.14.2

Screenshot / Video

https://cloudup.com/c2kEkexQRrW - it's the first few seconds on this video. This happened twice and I was able to record it the second time. Refreshing fixed it.

I was able to reproduce this a number of times in various environments (local dev, stage, prod..), but it no longer seems to occur for me. Can anyone else still reproduce?

The last time I was able to reproduce, I saw an error about the calypso host not being an allowed origin to access https://108380595987-j91sm1alavcdgd81i2655kp8q1lbtvrc.apps.googleusercontent.com

That's the google_oauth_client_id value used by the Google social login button (#).

I've no idea if it's related at all, but thought I'd mention it :confused:

Still happening. Reopening.
