Currently, I try to parse JSON to map[string][]interface{}, but unmarshalling returns an error. According to (<https://golang.org/pkg/encoding/json/>), to unmarshal JSON into an interface value, Unmarshal stores one of these in the interface value:

* bool, for JSON booleans
* float64, for JSON numbers
* string, for JSON strings
-[]interface{}, for JSON arrays
* map[string]interface{}, for JSON objects
* nil for JSON null

I wonder if golang is able to unmarshal map[string][]interface{}. The following is code snippet. I am new to Golang, thanks for help in advance.

```
// emailsStr looks like "{"isSchemaConforming":true,"schemaVersion":0,"unknown.0":[{"email_address":"test1@uber.com"},{"email_address":"test2@uber.com"}]}"

emailsRaw := make(map[string][]*entities.Email)
err := json.Unmarshal([]byte(emailsStr), &emailsRaw)

```

Error message:
