When uploading redirects.yaml into Labs, I get “upload failed” with the error [object Object]. It doesn’t tell me much. The entire redirects.yaml is below. Any ideas what’s going on?

The issue with your redirects.yaml are the two URLs containing ????.
In URLs, the ? character is reserved as it is used to indicate the start of a query string.
However, there’s a simple workaround: just encode the ? to something that can be interpreted by the server. The proper encoding would be %3F.
Here’s the encoded version of the redirects.yaml – tested it on one of my Ghost instances and it’s uploading and redirecting correctly
