No - I haven't checked

🐛 Describe the bug

See the 2 JSON files (with TXT extension because a file with JSON extension cannot be uploaded here). The input JSON file was processed BUT the snipped was not proceed. is a new construct in the DataCite schema. See the "results" JSON file for the results of processing the input JSON.

        "relatedItems": {
            "relatedItem": {
                "relationType": "IsPublishedIn",
                "relatedItemType": "Journal",
                "relatedItemIdentifier": {
                    "relatedItemIdentifierType": "DOI",
                    "#text": "10.3847/PSJ/aced50"
                },
                "titles": {"title": "R.G. French, D. Souami, Earth-based Stellar Occultation Predictions for Jupiter, Saturn, Uranus, Neptune, Titan, and Triton: 2023–2050 "},
                "publicationYear": 2023
            }
        },

The above JSON snipped should have been included the resulting DOI metadata.

🕵️ Expected behavior

I expected the doi-service to process the input JSON and include the JSON in the resulting output JSON (i.e., the output JSON should have included the in the DOI metadata).
