Error migrating Blogger content - parsing url prop

[whaleyr]

When I run the following command, I get an error message when processing blogger content.

migrate blogger --blogID 6521985176416791926 --apiKey <redacted>

I get the following log:

I re-ran the command with the verbose flag and got the following log
