Problem in unmarshalling the json file

[etefaghian]

Hello, I have a problem in unmarshalling one of the files that I previously entered in the form of xml in my program.
When I try to unmarshal an element that has tag:type for example :
"id": 13190773,
"tags": {
"type": "route",
}
I countered this error : unknown type of 'route'
Apparently there is a problem in recognizing types
Thanks in advance
