It looks like there is problem with alias settings. Look at config files in Craft 2 and 3 and find alias baseUrl. Is there any?

# Attempting Craft 2 -> 3 Upgrade | An Error occurred while handling another error

(Asked by: username_0 on 2018-10-08)

I'm trying to upgrade Craft 2 -> 3.
I can install Craft 3 no problem, but when I try starting over/upgrading I'm hitting this error.
The Craft 2 site is running the latest version of Craft.
MacOS High Sierra
MAMP Pro 5.0.4

When I continue anyway I get this error:
An Error occurred while handling another error:

### Answer by username_0 on 2018-10-09. Score: 1 | Accepted answer

For anyone who runs into the same error, my Craft 2 site had 3 environment settings:

Dev, Staging and Production.

This page covers how to carry those settings into Craft 3
<https://docs.craftcms.com/v3/config/environments.html>

Thanks to @username_1 for pointing me in the right direction!
