I have no idea what the Cannot convert object to primitive value is referring to. I hope you can point me in the right direction or instruct me how to debug this issue.

Thanks!

@RobThree this is mainly due to this:

your RSS feed is sending categories like this

[RobThree]

Ok. I'm sorry for my ignorance, but, what should it look like / be then?

[gautamkrishnar]

@RobThree nevermind, I just read through the RSS spec docs looks like this is also a valid case. Will try to add a fix for this. https://validator.w3.org/feed/docs/rss2.html#ltcategorygtSubelementOfLtitemgt

[RobThree]

That would be amazing! Thank you! Much appreciated!

(Also: I think blogger must've changed something yesterday then - I haven't changed anything)

[gautamkrishnar]

@RobThree fix for this is now released on https://github.com/gautamkrishnar/blog-post-workflow/releases/tag/1.8.4 Thanks for reporting this. There is no action is required from your end it will automatically work the next time when it runs.

All green! 🚀

Thanks! That was amazing and super quick! Much appreciated!
