Updating to hugo modules: XML syntax error

Describe the bug

I removed the git submodule as described here, and installed the hugo module. But then:

$ hugo mod get wangchucheng.com/hugo-eureka
go: no module dependencies to download
go: wangchucheng.com/hugo-eureka: unrecognized import path "wangchucheng.com": parsing wangchucheng.com: XML syntax error on line 1: expected /> in element
Error: failed to get ["-d" "wangchucheng.com/hugo-eureka"]: failed to execute 'go [get -d wangchucheng.com/hugo-eureka]': failed to execute binary "go" with args [get -d wangchucheng.com/hugo-eureka]: go: wangchucheng.com/hugo-eureka: unrecognized import path "wangchucheng.com": parsing wangchucheng.com: XML syntax error on line 1: expected /> in element
