Panic when markup.defaultMarkdownHandler is invalid #9968
Description
What version of Hugo are you using (hugo version)?
$ hugo version hugo v0.100.1-0afb4866e345d31cbbcbab4349e43f1d36122806 linux/amd64 BuildDate=2022-06-01T10:11:48Z VendorInfo=gohugoio
Does this issue reproduce with the latest release?
Yes!
Version v0.99.1 is able to generate my website (in the footer area you can see the version that is generated with). But both v0.100.0 and v0.100.1 throw the nil pointer dereference error:
hugo: no process found
