PrimeIntellect/SWE-rebench-V2 huggingface dataset:
Repository: ResearchObject/ro-crate-py (python)

Issue:
Allow root dataset to have more than one type
Fails if root dataset has an array as a value for @type 

eg. @type = ['Dataset', 'RepositoryCollection']

Note: @ptsefton says: Can we always code defensively, please.
