ERRORS: JSON Input Error + querySvr ECONNREFUSED_mongodb._tcp.pickaxecore.s2aib.mongodb.net

I keep getting these two errors in a very basic form pickaxe.
No Actions being used.
I can’t save work - Sometimes it deletes the pickaxe instructions entirely.

Hi @benhartley,

I am looking into the issue.

getaddrinfo EBUSY pickaxecore-shard-00-01.s2aib.mongodb.net

Appreciate the Loom, that made it easy to reproduce. I’ve filed this internally as PRD-484 so the builder team can chase down the JSON/ECONNREFUSED errors and the prompt data loss. I’ll update this thread once we’ve got a fix shipped.

Quick follow-up: the fix for PRD-484 just shipped, so builder saves should no longer throw the JSON Input Error or the Mongo ECONNREFUSED message. Please refresh the builder, try saving again, and let us know if you still see either error so we can dig deeper.
