term_reference field is not created
As the documentation you linked says, the structure for the fivestar field is the following.

{
  "field_fivestar":[{
    "rating":"100",
    "target":"0"
  }]
}


Probably you are missing "target"

Also, if you are using auto complete for taxonomy you should use the term id, tid, 3 times:

{
  "field_termins":[{
    "tid":{
      "tid":"[tid:26686]"
    }
   }]
}


Auto complete is the tricky part.
