Class Method Details

.clean_and_translate_content_type(content_type) ⇒ Object

Invalid JSON files with a content type of application/json will trigger 400 errors in sdr-api since they are parsed and rejected (not clear why and what part of the stack is doing this). The work around is to change the content_type for any JSON files to a custom stand-in and specific to avoid the parsing, and then have this translated back to application/json after . upload is complete. There is a corresponding change in sdr-api to translate the content_type back before the Cocina is saved. See github.com/sul-dlss/happy-heron/issues/3075 for the original bug report See github.com/sul-dlss/sdr-api/pull/585 for the change in sdr-api
