Why doesn't mediatopic.post want to send a text message to a group?

Question

Classmates

Hello,
I'm trying to send a test message to my group. I have rights
in the parameters I send:
gid - group id
attachment - {"media":[{"type":"text","text":"my text"}]}
to which I get this error:
100PARAM : Parameter ' gid' must be empty3gid
if gid is removed, it tries to send the user to STREAM.
tell me how the attachment should look in order for this to work?

To publish posts to a group, in addition to the group ID, you must specify the type of media topic ( type=GROUP_THEME )
