What steps does it take to reproduce the issue?

upload a json file to a dataset

• What happens?

The dataverse configuration for a json file is as follows:

https://github.com/IQSS/dataverse/blob/3305c4a41045d0bb2f261c5eb2aa93414a34f2c6/src/main/java/propertyFiles/MimeTypeDetectionByFileExtension.properties#L13

it is impossible to obtain a Hypothesis type json file with its corresponding MimeType:
application/x-json-hypothesis

Finally, it is not possible to obtain a preview provided by dataverse-previewers because there is no json file with the correct MimeType:

curl -X POST -H 'Content-type: application/json' http://localhost:8080/api/admin/externalTools -d \ '{ "displayName":"View Annotations", "description":"View the annotation entries in a file.", "toolName":"annotationPreviewer", "scope":"file", "types":["preview"], "toolUrl":"https://gdcc.github.io/dataverse-previewers/previewers/v1.3/HypothesisPreview.html", "toolParameters": { "queryParameters":[ {"fileid":"{fileId}"}, {"siteUrl":"{siteUrl}"}, {"key":"{apiToken}"}, {"datasetid":"{datasetId}"}, {"datasetversion":"{datasetVersion}"}, {"locale":"{localeCode}"} ] }, "contentType":"application/x-json-hypothesis" }'

• To whom does it occur (all users, curators, superusers)?

Any related open or closed issues to this bug report?

Start with the MIME mapping in src/main/java/propertyFiles/MimeTypeDetectionByFileExtension.properties at the linked line, then reproduce the JSON upload and inspect the externalTools request shown in the report. Compare the detected file type with application/x-json-hypothesis and establish whether the preview limitation is intentional or requires a configuration change.
