Is NodeBB's interoperability with Lemmy only for push-based messages?

[rglullis@communick.news]

Hello from Lemmy!

This message is both a test and a real question: I managed to subscribe to the NodeBB group, but I was not able to pull any conversation from there.

Maybe it's because Lemmy expects posts to be Page objects and NodeBB seem to be representing its topics as OrderedCollections?

I will post this and then send a followup comment with the output from browser.pub

I can see it just fine from MBin, so that's good at least

Got it from Lemmy.dbzer0.com

[hamiller@hub.hubzilla.hu]

The post has also arrived on hub.hubzilla.hu, a Hubzilla hub.

That looks very good overall.

No, pull works too. Lemmy doesn't support it, but technically you can pull the topic and then step through the collection. PieFed does support doing that (although NodeBB isn't always consistent at providing a JSON response, likely due to a CloudFlare caching issue).

If you want to do a pull that Lemmy supports from NodeBB, you need to choose the first post in the topic, not the topic.

E.g:
https://browser.pub/https://forum.wedistribute.org/post/12

That just a Note (with inReplyTo null) that Lemmy will recognise as the equivalent of a Page.

@rglullis@communick.news, a post from 7 days ago never made it to my instance:
