Unable to create elasticsearch mapping using postman - amazon-web-services

Question

I'm running elasticsearch image using docker.
Other services are running fine, like creating index, getting list of indices index.
But when i try to create mappings for already existing indices it returns the following error
{
"error": {
"root_cause": [
{
"type": "mapper_parsing_exception",
"reason": "Root mapping definition has unsupported parameters: mappings definition"
}
],
"type": "mapper_parsing_exception",
"reason": "Root mapping definition has unsupported parameters:mappings definition "
},
"status": 400
}
This is the mapping i'm trying to create
{
"mappings": {
"myfile": {
"dynamic": "strict",
"properties": {
"property1":{
"type":"keyword"
},
"property2":{
"type":"long"
}
}
}
}
}
URL i'm using to create mappings through postman
Method POST http://localhost:9200/my-domain-name/_mapping
in the body of the request i'm sending
above mappings
Elasticsearch image for docker is
elasticsearch:
container_name: tqd-elasticsearch
image: docker.elastic.co/elasticsearch/elasticsearch:7.0.1
environment:
- bootstrap.memory_lock=true
- "ES_JAVA_OPTS=-Xms512m -Xmx512m"
- discovery.type=single-node
depends_on:
- "localstack"
logging:
driver: none
ports:
- 9300:9300
- 9200:9200
networks:
- "local"
networks:
local:
driver: "bridge"
What am I doing wrong over here?

Elasticsearch has deprecated _type of index from Elasticsearch 7.x version.
You can use below request from Postamn and it will work for you.
URL: POST http://localhost:9200/my-domain-name/_mapping
{
"dynamic": "strict",
"properties": {
"property1": {
"type": "keyword"
},
"property2": {
"type": "long"
}
}
}
