Hugo works locally but it crashes when triggered as post-receive hook

I followed this tutorial to deploy my Hugo blog as a post-receive Git hook.

I make changes locally, push to my server and that triggers the post-receive hook, which in turns runs something like:

/usr/bin/hugo -s $WORKING_DIRECTORY -d $PUBLIC_WWW

That results in the following crash:

remote: running hugo
remote: Started building sites ...
remote: panic: runtime error: slice bounds out of range
remote: goroutine 126 [running]:

If I run the same script from a SSH session in my prod server everything works just fine. The issue is not related to working directories, as the paths are all absolute. I’m using the same username for both my SSH session and the Git remote, so it shouldn’t be a permissions thing.

Do you know why this is happening? The error message is not really helpful.

You are right about the error message … This issue should be fixed in Hugo 0.18-DEV (the upcoming release).

You may get some input by reading this:

That did it!

I had other tags though, legacy from a WP import: <!--:es--> etc. Removing them fixed the issue.

Thanks a lot!
