👋 Hi, I just hit a “GraphQL error” when accessing the “Backfills” page. Here are the details:
Copy code
Operation name: InstanceBackfillsQuery

Message: 'NoneType' object has no attribute 'deserialize_subset'

Path: ["partitionBackfillsOrError","results",4,"numPartitions"]

Locations: [{"line":7,"column":9},{"line":62,"column":3}]
This is using dagster
1.1.10
. I can provide more details. Should I open a GH issue?

hello! Please open an issue yes, this looks unexpected

Alright, I’ll do that next time. This has gone away, presumably it was caused by some bad state when running locally.

we observed this elsewhere as well. I just filed this issue to track: https://github.com/dagster-io/dagster/issues/11787

This error happens for me when simply visiting the backfills page
s
A fix for this is landing in Dagster's next release

Great, thanks!
