The user is encountering a deployment error when trying to deploy a messaging channel with more than 4 autoresponses. The UI allows configuring up to 5 autoresponses, but the deployment fails with an error message stating that only 4 autoresponses are supported.
Deploy 4 auto-responses via metadata and manually add the 5th component directly in the target environment through the UI after deployment.
The deployment error occurs because there's a hard-coded limit of 4 messaging channel autoresponses enforced by the Metadata API, Workbench, Change sets(not supported), Salesforce DX, and CI/CD tools.
