[BUG] Unable to upload Excel sheet files

[marmoure]

The problem

When trying to upload xlsx files using eXide to the db I get this error:

The XML parser reported a problem: fatal error at (1,1) : Content is not allowed in prolog. XMLDB reported an exception while storing document: The XML parser reported a problem: fatal error at (1,1) : Content is not allowed in prolog.

The Expected outcome

The file upload to happen without any error.

The following conversation happened on Element slack: https://elemental-xyz.slack.com/archives/C08J2KMEW23/p1775560143671479
It seems like there a bug in the media type mapping file where it tries to map xlsx to XML.

The file upload also fails via XMLRPC, e.g. with oXygen:

Operation 
Import Files

...myfile.xlsx
org.apache.xmlrpc.XmlRpcException: Failed to invoke method parseLocalExt in class org.exist.xmlrpc.RpcConnection: org.xml.sax.SAXException: The XML parser reported a problem: fatal error at (1,1) : Content is not allowed in prolog.
org.xml.sax.SAXException: fatal error at (1,1) : Content is not allowed in prolog.
org.xml.sax.SAXParseException; systemId: file:///tmp/exist-db-temp-file-manager-2663348685812551276/exist-db-temp-16639411356743654351.tmp; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.

Forcing it via curl as octet-stream does the trick:

curl -v --user admin \
  -H 'Content-Type: application/octet-stream' \
  -T '...myfile.xlsx' \
  'https://myserver/exist/rest/db/apps/myapp/myfilexlsx'
