400 Bad Request for frappe.cloud API - api

Question

I'm getting 400 Bad Request for frappe.cloud API, when I'm trying to call it using golang code using http.NewRequest, this API is working fine when I check it using postman. following is the API
https://xxxx.frappe.cloud/api/resource/Item?fields=["name","item_name","item_group","description"]&filters=[["Item","item_group","=","xxx Product"]]
If I use the same golang code to call same API with out filters it works fine. following is the working API
https://xxxx.frappe.cloud/api/resource/Item?fields=["name","item_name","item_group","description"]
code as follows
func FetchProperties(dataChannel models.DataChannel) (map[string]interface{}, error) {
thisMap := make(map[string][]map[string]interface{})
client := &http.Client{}
req, err := http.NewRequest("GET", dataChannel.APIPath, nil)
if err != nil {
commons.ErrorLogger.Println(err.Error())
return nil, err
}
eds, err := GetDecryptedEDSByEDSID(dataChannel.EDSId)
if err != nil {
commons.ErrorLogger.Println(err.Error())
return nil, &commons.RequestError{StatusCode: 400, Err: err}
}
req.Header.Set("Content-Type", "application/json")
req.Header.Set("Authorization", eds.DataSource.Auth.Token)
response, err := client.Do(req)
if err != nil {
commons.ErrorLogger.Println(err.Error())
return nil, err
}
data, err := ioutil.ReadAll(response.Body)
if err != nil {
commons.ErrorLogger.Println(err.Error())
return nil, &commons.RequestError{StatusCode: 400, Err: err}
}
if response.StatusCode == 200 {
err = json.Unmarshal(data, &thisMap)
if err != nil {
commons.ErrorLogger.Println(err.Error())
return nil, &commons.RequestError{StatusCode: 400, Err: err}
}
return thisMap["data"][0], err
} else {
return nil, &commons.RequestError{StatusCode: response.StatusCode, Err: errors.New("getting " + strconv.Itoa(response.StatusCode) + " From Data channel API")}
}

Postman has an option to convert request to programming language equivalent.
Here is a working go code for sending the request. package main
import (
"fmt"
"strings"
"net/http"
"io/ioutil"
)
func main() {
url := "https://xxx.frappe.cloud/api/resource/Item?fields=%5B%22name%22,%22item_name%22,%22item_group%22,%22description%22%5D&filters=%5B%5B%22Item%22,%22item_group%22,%22=%22,%22xxx%20Product%22%5D%5D%0A"
method := "GET"
payload := strings.NewReader(`{
"payload": {},
"url_key": "",
"req_type": ""
}`)
client := &http.Client {
}
req, err := http.NewRequest(method, url, payload)
if err != nil {
fmt.Println(err)
return
}
req.Header.Add("Content-Type", "application/json")
req.Header.Add("Cookie", "full_name=foo; sid=secret_sid; system_user=yes; user_id=foobar; user_image=")
res, err := client.Do(req)
if err != nil {
fmt.Println(err)
return
}
defer res.Body.Close()
body, err := ioutil.ReadAll(res.Body)
if err != nil {
fmt.Println(err)
return
}
fmt.Println(string(body))
}
