Question

Hi there I m trying to provision a custom hostname for an Azure Function When I work through this in the portal I have to complete a domain verification step to prove ownership of the host name I m trying to provision adding a `TXT` record to my DNS with a specific GUID If this step is not completed the Pulumi `CustomHostnameBinding` fails to create and the Pulumi update as a whole fails ```Error creating updating Custom Hostname Binding App Service exampleappservice7422ec00 Resource Group exampleresourcegroupa1b4af45 web AppsClient CreateOrUpdateHostNameBinding Failure responding to request StatusCode=400 Original Error autorest azure Service returned an error Status=400 Code= BadRequest Message= A TXT record pointing from to 2f77eba357071f06b1ae4cb900105eeb8236f2697466a15641af4fdd75f2fb49 was not found Details= Message A TXT record pointing from to 2f77eba357071f06b1ae4cb900105eeb8236f2697466a15641af4fdd75f2fb49 was not found Code BadRequest ErrorEntity Code BadRequest ExtendedCode 04006 Message A TXT record pointing from to 2f77eba357071f06b1ae4cb900105eeb8236f2697466a15641af4fdd75f2fb49 was not found MessageTemplate A TXT record pointing from asuid 0 to 1 was not found Parameters 2f77eba357071f06b1ae4cb900105eeb8236f2697466a15641af4fdd75f2fb49 ``` I haven t been able to catch this error nor identify a way from the docs poking around the Pulumi libraries with code completion etc etc to capture the resource s in error and inspect the returned error What I d like to be able to do is intercept this error provision the `TXT` record in CloudFlare DNS retry the operation then delete the `TXT` record again I m using the < CJ909TL6P|typescript> SDK

Do you want to do all this in an automated fashion

Ideally yes

It would be amazing if the `CustomHostnameBinding` had an argument option whatever that accepted a DNS provider resource so we could do something like ```new CustomHostnameBinding example binding hostname <http www mywebsite com|www mywebsite com> appServiceName exampleAppService name resourceGroupName exampleResourceGroup name dnsVerificationRecord new cloudflare Record azure appservice domain verification name azure appservice domain verification zoneId whatever type TXT value value from the error message ttl 3600 ```

< tall librarian 49374> Is what I m asking currently possible or do we need to complete the DNS verification step by hand somehow I m struggling to understand how a `CustomHostnameBinding` can ever succeed at first
