What's the issue?

It's currently not possible to define asset jobs of multi assets where the asset specs have different partitions definitions. Looks like this was missed in #23824.

The error surfaces when you want to use try to materialize a subset of assets in a graph of assets that contain different partitions definitions.

What did you expect to happen?

It should be possible to run a subset of assets in a graph of assets that have different partitions definitions.

How to reproduce?

import dagster as dg

spec1 = dg.AssetSpec("asset1", partitions_def=dg.StaticPartitionsDefinition(["a", "b"]))
spec2 = dg.AssetSpec("asset2", partitions_def=dg.StaticPartitionsDefinition(["x", "y"]))
dg.AssetsDefinition(specs=[spec1, spec2])  # Raises DagsterInvalidDefinitionError
