Add subdomain to amplify app via code

[manikpokhetra79]

Hi, I have been working to add subdomains to my amplify app. I have added a domain to the amplify app.

• If I add a subdomain to amplify app manually, it works fine.
• But for my requirements, I need this subdomain additional process to be done via code.
• I only found two APIs create domain association and updatedomainassociation, but neither one is exactly what I need.
• CreateDomainAssociation API is not adding the new subdomain to the app at all.
• Update domain association API removes the old subdomains if i only add a new subdomain to the request, but if I add all existing and new one. It adds the new one. Though this method is very risky and not acceptable.

Any suggestions or ideas on how to achieve subdomain association via code.
