hey @roadscape,
facing same issue as reported by @penguinpablo, my function call is about discussions by created though.
I tried both steemjs (steem.api.getDiscussionsByCreated(query, async function (err, result)) and dsteem (client.database.getDiscussions('created', query)), both returning server errors when tested on https://api.steemitdev.com, while they work properly on https://api.steemit.com
useAppbaseApi did not solve it either for steemjs
Thoughts?
