I can't access the ZOHO creator form in ZOHO CRM.

I can't access the ZOHO creator form in ZOHO CRM.

Hi Guys,

I Build App in Zoho Creator as the name of "Add Account" and written Delegu code for saving the Account/Contacts records into ZOHO CRM, it's working fine smoothly saving the records into ZOHO CRM.

I am facing a problem that when I tried to access the "Add Account" App in Zoho CRM through (Setting --> Web tabs--> Links) I am getting an error message of "Sign in to your Zoho account to view this Form." along with a sign-in button, I have clicked many times to get into form but no luck, but my browser logged in with my credentials and other modules and forms are opening fine.

IMG_001 - Error page
IMG_002 - Deluge Code 
IMG_003 - Web tab settings

When I save and click the link I am redirecting IMG_001. The version I am using is Enterprise.

I have attached the screenshot of the error page and Delugecode, please give your suggestions.

I followed this link: https://help.zoho.com/portal/en/kb/crm/integrations/zoho/zoho-creator/articles/link-zoho-creator-apps#Prerequisite

Thanks.
