It appears to have solved the error in my end. Might need to be documented just in case.

I have added a note in the docs: [Update Defer.md · gohugoio/hugoDocs@807be5d · GitHub](https://github.com/gohugoio/hugoDocs/commit/807be5dbf30e145a6ea207756505714eda60c601)

I will also try to find some time to 1) Test this and 2) Throw an error if we can detect this.
