Where's the token from login endpoint? #api


In the log which follows, I have redacted sensitive information.
When I run curl (for a crude test) from an Ubuntu Linux 20.04 system using the /login endpoint, providing valid email and password, I get back the following JSON (re-formatted by jsonlint.com website). There is no error indicated that I can see. So...where's the "token": "", section that's supposed to be near the end of the JSON response?
Without the token, I can't really perform any other API operations, no? I have reread https://groups.io/api#login and cannot seem to locate the error.
