Error Handling in golang

I need to handle errors with error code and return errors in JSON format like below.

{
    "errorCode":400,
    "errors":[
        {
            "errorField":"dispachNumber",
            "errorDescription": "This is not a valid dispatch Number"
        },
        {
            "errorField":"phone",
            "errorDescription": "Phone numbers must be in the XXX-XXX-XXXX format"
        }
    ]
}

{
    "errorCode":500,
    "errors":[
        {
            "errorDescription": "there was an internal server error"
        }
    ]
}

My problem is how to handle this way , here i am able to do with single error only but when i do with multiple errors it return only one error struct , see code how i am doing this.

Errors := ErrorHandle(403, "User Id", "User Id must be of integer type")
Errors = ErrorHandle(403, "Phone Number", "Phone Number type")

and ErrorHandle() function as 

func ErrorHandle(ErrorCode int, ErrorFields, ErrorDesc string) []Errors {
    AllErrors := []Errors{}

    if len(AllErrors) > 0 {
        AllErrors = IterateErrors(AllErrors, ErrorCode, ErrorFields, ErrorDesc)
    } else {
        Errorsvalue := Errors{
            ErrorCode: ErrorCode,
        }
        Error := Error{}
        Error.ErrorFields = ErrorFields
        Error.ErrorDescription = ErrorDesc
        Errorsvalue.ErrorDesc = append(Errorsvalue.ErrorDesc, Error)

        AllErrors = append(AllErrors, Errorsvalue)
    }
    return AllErrors
}

Thanks in Advance !

You're always creating a new empty AllErrors slice, adding a single error to it, then returning it.

Your ErrorHandle should either take the existing list of errors and append to it or you should have a custom type Errors []Error used as such:

type Errors []Error
func (Errors *e) ErrorHandle(...) {
  ...
  e = append(e, <new error>)
}

Errors myerrors;
myerrors.ErrorHandle(<first error>)
myerrors.ErrorHandle(<second error>)

This is just high-level code, you should be able to fill in the rest.
