Hiii,

I need to submit a form. When it is a non-incognito mode, the form gets submitted. But if I am trying to send it from icognito window, it will throw error as “INVALID HUTK”.

I have written a condition as

`$hubspotutk = isset($_COOKIE['hubspotutk']) ? $_COOKIE['hubspotutk'] : 'hutk';`

I had tried with empty cookie value as

`$hubspotutk = isset($_COOKIE['hubspotutk']) ? $_COOKIE['hubspotutk'] : '';`

But it throwed the same error as above.

Is there any way to handle form submission in incognito mode???

Can someone help please?

Hey @newMember,

How are you passing the cookie if there’s no cookie? If you’re passing in an empty cookie, the Form submission would throw the following error:

- INVALID\_HUTK - The `hutk` field in the `context` object is invalid.

If you’re indeed passing in an empty cookie, I’d suggest for you to implement this logic:

1. Check if hutspotutk is present

2. If it’s present, include it in the form data

3. If it’s not present, the form data should not have the context hutk.

In our case, if we do not pass a **hutk** , then we get an error 400.

How can I send a request with an empty value **hutk?**
