@Venkatakrishnan J Have you tried to use the ARM template given here in this link for UrlRewrite.?
"name": "UrlRewrite",
"parameters": {
"@odata.type": "#Microsoft.Azure.Cdn.Models.DeliveryRuleUrlRewriteActionParameters",
"destination": "string",
"preserveUnmatchedPath": "bool",
"sourcePattern": "string"
}
If so, does it give you an error when you try this? Please let me know. Thank you!
