Hugo --minify: failed to render pages

Hi there,

@zwbetz told me to open a thread here:
I am trying to use the --minify switch in hugo v51. But it gives me errors I cannot understand:

hugo server:

The output of the --minify run is very confusing - the ^ point to valid html.

Any pointers how to fix it?


Hi Max. Thanks for opening this topic. If you would, please share a link to your site code so that we can attempt to reproduce the issue.

For others, here’s the original GH issue:

Hi there,

here is the repo:


I get this error when trying to access it. You probably need to make it “public” or something like that.

Strange - it’s public and the page renders fine for me. Please try again, maybe a temporary issue.

Just tried again. I get the same error.

Another option is to zip up your source code and post it here.

I’ve had a look at your repository. This probably won’t solve your problem, but is there a reason why the wp-uploads directory is inside your content directory, rather than the static directory? It looks to me to be full of images and other binary files which don’t need to be manipulated by Hugo.

Sure, I could move that - I migrated from Wordpress and the migration tool did that.

@funkydan2 Did not solve it - any further ideas?

I cloned it to github:

Remove the single quotes on lines 56-57 in the footer partial:

Then check your JSON and JavaScript syntax everywhere else.

remove the single quotes, no change.
Then I emptied my content folder and added the posts back and it somehow errors out when generating the page description:

The generated markup is not valid because of the <a href=" part.
Is that a hugo issue or should I report that in the minify component repo?


This line is the one generating that html that is causing your error.

What happens is that the specific post on your screenshot is using the post’s .Summary, to generate the value for description, which contains html.

Specifically, it contains <a href="... .

In the html body, that would be valid markup, however, this line is being generated in the head, as value for json, and so the double quotes there makes the json invalid.

Perhaps if you pipe the .Summary through plainify it might help?


thanks a bunch, that worked!
