Hi folks, I’m having an issue with partitioning. I’ve got an asset that depends on an upstream asset which is using
. The downstream asset is also using dynamic partitions. When executing the downstream asset after confirming that the upstream asset has run and all partitions are populated, I get the following error:
Copy code
dagster._core.errors.DagsterInvalidInvocationError: Partition range wicked_folder/basic_csv4.csv to wicked_folder/basic_csv1.csv is
        not a valid range. Nonexistent partition keys:
        ['wicked_folder/basic_csv4.csv', 'wicked_folder/basic_csv1.csv']
In the screenshot attached to this reply you can see that the partitions have run in the upstream node. The odd thing is that if I opt to run a backfill on only 1 partition, then the asset is materialized as I would expect. screenshots in the reply
this first screenshot shows that all upstream partitions have run the second screenshot shows the error message when trying to run more than 1 asset
also when i run the backfill i get a warning that says the upstream files dont exist, but can confirm that they do. I bumped my dagster/dagit version to 1.2.7 since it looked like this was an issue in an earlier version, but I'm still getting the problem
Hi Robert. Do the upstream and downstream dynamic partitions defs have the same name?
@Robert Kolb did you ever resolve this? I’m having the same issue
