Unmarshal error with golang on AWS Lambda, works locally

I created code in golang that is supposed to support the endpoint API (through get queries). That's documentation of API's endpoint: https://developer.dotdigital.com/docs/get-all-campaigns

Code looks like this:

type Campaign struct {
    Id          int    `json:"id,omitempty"`
    Name        string `json:"name,omitempty"`
    Subject     string `json:"subject,omitempty"`
    FromName    string `json:"fromName,omitempty"`
    FromAddress struct {
        Id    int    `json:"id,omitempty"`
        Email string `json:"email,omitempty"`
    }
    HtmlContent      string `json:"htmlContent,omitempty"`
    PlainTextContent string `json:"plainTextContent,omitempty"`
    ReplyAction      string `json:"replyAction,omitempty"`
    IsSplitTest      bool   `json:"isSplitTest,omitempty"`
    Status           string `json:"status,omitempty"`
}

func (dcfg DotmailerApiConfig) GetContacts2() ([]*dotmailermodels.Contact) {
    var (
        allContacts, respContacts []*dotmailermodels.Contact
        selected                  = 1000
        skip                      = 0
        err error
    )
    for true {
        url := dcfg.Url + fmt.Sprintf("v2/contacts?withFullData=%s&select=%s&skip=%s",
            strconv.FormatBool(false),
            strconv.Itoa(selected),
            strconv.Itoa(skip))
        resp := dcfg.GetRequesDotmailertBuilder(url)
        err = json.Unmarshal(resp, &respContacts)
        if err != nil {
            Error.Println(err) // just error trace
        }
        allContacts = append(allContacts, respContacts...)
        if len(respContacts) == 1000 {
            skip += 1000
            respContacts = nil
            continue
        }
        break
    }
    return allContacts
}

When I'm running on my PC I get the correct response. When I use it in Lambda I get this error:

[ERROR] 2019/03/24 18:37:26 dotmailergetrequests.go:110: json: cannot unmarshal object into Go value of type []*dotmailermodels.Campaign

Have you got any idea why?

I found that error. Everything was correct - except password import in the other file.

try this:

type Address struct {
    Id    int    `json:"id,omitempty"`
    Email string `json:"email,omitempty"`
}
type Campaign struct {
    Id          int    `json:"id,omitempty"`
    Name        string `json:"name,omitempty"`
    Subject     string `json:"subject,omitempty"`
    FromName    string `json:"fromName,omitempty"`
    FromAddress *Address `json:"fromAddress,omitempty"`
    HtmlContent      string `json:"htmlContent,omitempty"`
    PlainTextContent string `json:"plainTextContent,omitempty"`
    ReplyAction      string `json:"replyAction,omitempty"`
    IsSplitTest      bool   `json:"isSplitTest,omitempty"`
    Status           string `json:"status,omitempty"`
}
