Zoho Desk - Custom Extension - whiteListedDomains

Zoho Desk - Custom Extension - whiteListedDomains

I am trying to use the ZOHODESK.Request function with a connection to Zoho CRM via Sigma.

When I attempt the method call, I receive the message:

"No entry found in plugin-manifest whiteListedDomains for requested URL"

This is despite populating the plugin-manifest-json:
  1. "whiteListedDomains": [
    "https://*.zohoapis.eu",
    "https://127.0.0.1:5000",
            "https://mydomain.com"
    ],
I have added multiple domains (mydomain.com = custom Desk domain) as I have tried multiple combinations and I am unable to see which domain I need to add to the file.

Code sample attached.
