<en-media/> does not presented in note content on create

[diachkow]

So, I have a next note XML rendered in my application (the telenote_api prefix is just a name of my docker container):

telenote_api | <?xml version="1.0" encoding="UTF-8"?>
telenote_api | <!DOCTYPE en-note SYSTEM "http://xml.evernote.com/pub/enml2.dtd">
telenote_api | <en-note>
telenote_api |     Видеокурс по разработке на Python

telenote_api |         <en-media type="image/jpeg"

telenote_api |     
telenote_api | </en-note>

But when the note is craeted the picture is not presented in it:

Am I doint right? Note, that I'm currently using Evernote sandbox (dev) server.

I've also tried to do it manually via python3 shell:

>>> note.content = r'<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE en-note SYSTEM "http://xml.evernote.com/pub/enml2.dtd"><en-note><en-media width="640" height="480" type="image/jpeg" hash="f03c1c2d96bc67eda02968c8b5af9008"/></en-note>'
>>> 
>>> 
>>> 
>>> note_store.createNote(note)
Note(guid='93051571-0db3-4fda-a38c-3a41fe9faa2b', title='Image', content='<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE en-note SYSTEM "http://xml.evernote.com/pub/enml2.dtd"><en-note><en-media width="640" height="480" type="image/jpeg" hash="f03c1c2d96bc67eda02968c8b5af9008"/></en-note>', contentHash=b'\xd0\xfa\xb4P\xe2\xc0\t\xc3\xa0k\xf3\xf7\xc1\xa9\xdep', contentLength=216, created=1594209967000, updated=1594209967000, deleted=None, active=True, updateSequenceNum=102, notebookGuid='e15ed359-9313-4328-a02a-a1a55e23478a', tagGuids=None, resources=None, attributes=NoteAttributes(subjectDate=None, latitude=None, longitude=None, altitude=None, author=None, source=None, sourceURL=None, sourceApplication=None, shareDate=None, reminderOrder=None, reminderDoneTime=None, reminderTime=None, placeName=None, contentClass=None, applicationData=None, lastEditedBy=None, classifications=None, creatorId=None, lastEditorId=None), tagNames=None)

But still got no result:
