Error with using series

If you are maintained your own bilberry-hugo-theme and had updated your theme from an older version recently,

and you are using Series,

you might got this error when you run hugo or hugo server to generate your static site page:

• ERROR 2023/01/05 00:24:37 render of "page" failed: execute of template failed: template: _internal/opengraph.html:36:44: executing "_internal/opengraph.html" at <.>: range can't iterate over YOUR_SERIES_NAME

Just early than Issue-459: Fix Open Graph metadata #463 at HEAD 0971422,
you will got this error because the new metadata format.

Fixed

It's a simple thing to fix it, it caused by the new format of metadata:

• Old => series: 'Your Series Name'

• New => series: [ 'Your Series Name' ]

As you can see here, just use series with [] character contained.

And here's something new in the new metadata, just watch Bilberry Hugo Theme Guidence for more info.

Here's the short brief below:

videos: ["/video/test_mp4_video.mp4"]
series: ["Your Series Name"]

Notice: The official Guidence in open-graph-metadata have no this description about series: ["Your Series Name"], so I add it to here in the last line.

This is the error log below:

[gitaeron]

If you got Error when you using bilberry hugo theme, just calm down and check everything that needed.

And if it's out of your range, just start a Discussion and seek for help from others, and searched some key words first is a good idea.
