I have this mapping
PUT /mytest
{ "mappings":{ "properties": { "value": { "type": "object" } } }
}When I insert this document
POST /mytest/_doc/4
{ "value": { "value": "test"}
}I got the following error:
{ "error": { "root_cause": [ { "type": "mapper_parsing_exception", "reason": "failed to parse field [value.value] of type [long] in document with id '4'. Preview of field's value: 'test'" } ], "type": "mapper_parsing_exception", "reason": "failed to parse field [value.value] of type [long] in document with id '4'. Preview of field's value: 'test'", "caused_by": { "type": "illegal_argument_exception", "reason": "For input string: \"test\"" } }, "status": 400
}I know the naming convention is bad, still, this is a valid JSON request, not sure why it doesn't allow it.

This error is telling you that you don't have a mapping for the property value within your value object property. The below example would property set the value.value property within your mytest index:
PUT mytest
{ "mappings": { "properties": { "value": { "type": "object", "properties": { "value": { "type": "text" } } } } }
}However, I don't think that's what your intention was. As a best practice, try following the Elastic Common Schema (ECS) for naming your index properties.
