What are the steps to reproduce the issue?

I want to create a gateway dns rule to block domains resolving to a specified country.

async function createDNSRule(accountId) {
// Cloudflare API endpoint for creating DNS rules (using account ID)
const endpoint = https://api.cloudflare.com/client/v4/accounts/${accountId}/gateway/rules;

// Define the DNS rule (same as before)
const rule = {
“action”: “block”,
“description”: “Block DNS queries”,
“expression”: “dns.dst.geo.country in {"RU", "CN", "IR"}”,
“paused”: false,
“priority”: 1,
};

// Make the API request (using API token)
try {
const response = await fetch(endpoint, {
method: ‘POST’,
headers: {
‘Content-Type’: ‘application/json’,
‘Authorization’: Bearer ${your_cloudflare_api_token}, // Use API token for authorization
},
body: JSON.stringify(rule),
});

if (response.ok) {
  const data = await response.json();
  console.log('DNS rule created successfully:', data);
} else {
  console.error('Error creating DNS rule:', response.status, response.statusText);
}

} catch (error) {
console.error(‘Error creating DNS rule:’, error);
}
}

// Replace with your actual account ID
const accountId = ‘My ID’;

// Replace with your actual API token
const your_cloudflare_api_token = ‘My Token’;

// Call the function to create the DNS rule
createDNSRule(accountId);
