Error Importing Categories from a Discourse Instance to Another

Support
1

Hi Discourse team!

I’m running into an error when I tried to export a category from our staging environment to our production. For context we have a bunch of topics in staging that we wish to publish on production and copy-pasting would take a long time.

Here is the error I run into after running discourse import_category category-export-2022-02-14-042606.json based off this tutorial:

Starting import from category-export-2022-02-14-042606.json...

I only wish to export the category, so I’m not sure what it’s complaining about the groups.

Any help would be greatly appreciated!

Cheers,
Tim

Just bumping and seeing if anyone else has experienced this issue?

I think that the script tries to import everything.

You might see if you can edit the group out of the json or modify the script to skip the group.

Hi @pfaffman ,

Thanks for your response!

What do you mean by everything? I’ll give that a go and edit the groups out of the json. I thought the tutorial was only for categories / topics so I didn’t expect it to give me a lot more than that

Will report back once I test it!

It’s a slippery slope. You can’t create the topics without the users, and then on it goes.
