One or more datasets in Harvard Dataverse have handles that point to an error page instead of the dataset.

For example, https://hdl.handle.net/1902.1/00021 is the handle of the dataset at https://doi.org/10.7910/DVN/4MRH2N. And as of Oct 22, 2024, that handle points to a Not Found page instead of the dataset page.

Another dataset's handle, https://hdl.handle.net/1902.1/HIJLKAJELN, does lead to the dataset.

I'm not sure if:

• there are other handles in Harvard Dataverse that don't point to the dataset
• how long https://hdl.handle.net/1902.1/00021 has been pointing to an error page
• if the process used to register DOIs for datasets that had handles caused some handles to not redirect
• if in the future that process would cause the handles of other datasets to point to error pages instead of the dataset pages, such as the datasets discussed in a recent GitHub issue about possibly migrating datasets into Harvard Dataverse.

@sbarbosadataverse also noticed that the handle that does point us to the dataset, https://hdl.handle.net/1902.1/HIJLKAJELN, redirects to https://dataverse.harvard.edu/dataset.xhtml?persistentId=hdl:1902.1/HIJLKAJELN, where the persistentId in the URL is the handle. And she wondered if we should expect that handle to redirect to https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/RWFQKC instead, where the persistentId in the URL is the DOI.
