`Error parsing response` on cloud instance, works locally (Go 1.24, latest SDK)

[Dhruv-Sachdev1313]

I’ve been stuck on an issue for quite a while and could really use some help or guidance.

Environment

• Go version: go1.24
• Kite Connect Go SDK: latest (v4)
• Works fine on: Local machine
• Fails on: Cloud instance (Ubuntu 22.04.5 LTS)

---

Problem

When using the SDK methods like GetQuote() or GenerateSession() on the cloud instance, I keep getting:

failed to fetch quotes from Kite: Error parsing response

Here’s a minimal reproducible snippet:

quotes, err := kiteClient.GetQuote(kiteSymbols...)
if err != nil {
    return nil, fmt.Errorf("failed to fetch quotes from Kite: %w", err)
}

And for session generation:

userSession, err := k.kiteClient.GenerateSession(requestToken, k.config.ApiSecret)
if err != nil {
    return nil, fmt.Errorf("failed to generate session with Kite: %w", err)
}

Both result in:

Error parsing response

---

What's strange

When I bypass the SDK and use a manual http.Post for generating the session, it works perfectly fine on the same instance:

// Simplified manual version of GenerateSession that works
req, _ := http.NewRequest("POST", "https://api.kite.trade/session/token", requestBody)
req.Header.Set("Content-Type", "application/x-www-form-urlencoded")
client := &http.Client{}
resp, _ := client.Do(req)
// ... unmarshal JSON manually — works fine

---

What I’ve tried

• Checked network access (curl requests work)
• Debug mode enabled — SDK returns Error parsing response with no additional details
• Same API key/access token used on both local and instance

---

Question

Is the SDK expecting something in the response that could be failing silently if the format is different?

Also:

• Does the SDK use any specific Go net/http behavior or TLS config that might differ in cloud environments?
• Can we get the raw response from the SDK before it attempts JSON unmarshaling?

---

Any direction to help debug this would be hugely appreciated. Happy to share more logs or details as needed.

Thanks in advance!

Additional Info

Just to clarify — some other API calls using the SDK do work fine even on the same instance.

For example, this works without any issue:

margins, err := kiteClient.GetUserMargins()
if err != nil {
    return nil, fmt.Errorf("failed to fetch balance from Kite: %w", err)
}

So it seems like the issue is specific to certain endpoints like GenerateSession() and GetQuote() which might be returning something the SDK cannot parse properly.

This adds to the confusion, since it confirms network access and basic SDK usage is working on the instance.

Would appreciate any insights or suggestions!

Hi

@Dhruv-Sachdev1313

Looked at the code - the only thing that can actually fail during unmarshalling in both UserSession and Quote is the time parsing (models.Time), which calls time.LoadLocation("Asia/Kolkata") under the hood. Margins
doesn't have any time fields, so that tracks with it working fine on your end.

On a regular Ubuntu install this should just work since tzdata is there, but if you're running the binary inside a container or something stripped down it might not have it. Can you try running this on the instance where
it breaks?

  package main

  import (
      "fmt"
      "time"
  )

  func main() {
      loc, err := time.LoadLocation("Asia/Kolkata")
      fmt.Println("loc:", loc, "err:", err)
  }
