Issue Summary

This is reproducible on Data Center: (No)

For connect-to-forge apps, when the forge app is installed on confluence instance with custom domain, the connect lifecycle install event that gets triggered, has the payload with baseUrl and displayUrl both set to custom domain, rather then the *.atlassian.net domain for baseUrl . This prevents the install event function from making calls to confluence API endpoints, since they need the URL to be in *.atlassian.net format.

Steps to Reproduce

1. Setup custom domain for confluence instance
2. Create a connect app with install lifecycle event and install it to the confluence instance. We can use go.atlassian.com/connect-inspector 
3. Follow the connect to forge guidelines to create a forge app. An example, manifest

   app:
     runtime:
       name: nodejs22.x
     id: ari:cloud:ecosystem::app/<forge_app_id>
     connect:
       remote: connect
       key: <connect_app_key>
   connectModules:
     "confluence:lifecycle":
       [
         {
             "key": "connect-lifecycle",
             "installed": "/log-save/installed"
           }
       ]
   remotes:
     - key: connect
       baseUrl: https://connect-inspector.services.atlassian.com/resources/f4b8d764-5084-4df3-8673-11b405bc1e15
   permissions:
     scopes: [ "read:connect-confluence" ]
   

4. install the forge app on a confluence instance.

   forge deploy && forge install -s internal.confluence.customdomain.info -p confluence
   

5. Observe the payload received at the install lifecycle function in connect-inspector.

Expected Results

In the event payload baseUrl  should be [subdomain].atlassian.net and displayUrl should be the custom domain name.

Actual Results

In the event payload baseUrl and displayUrl are both set to custom domain. Below is an sample from a test: 

{
  "key": "ac.ci.f4b8d764--snipped--",
  "clientKey": "9938efd4--snipped--",
  "sharedSecret": "--snipped--",
  "baseUrl": "https://internal.confluence.customdomain.info/wiki",
  "productType": "confluence",
  "description": "Atlassian Confluence",
  "eventType": "installed",
  "cloudId": "16c33e5d-60d9-4922--snipped---",
  "installationId": "ari:cloud:ecosystem::installation/4853d4d2-f573--snipped--",
  "publicKey": "--snipped--",
  "serverVersion": "6452",
  "pluginsVersion": "1000.0.0.ibecnb19hj56",
  "displayUrl": "https://internal.confluence.customdomain.info/wiki"
} 

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
