My app works locally and rsconnect is linked to my account. When I try to deploy, the app gets created on my shinyapps.io account, but I get an error message shown below and the app is displayed as undeployed.
Warning: the existing manifest.json file will not be used or considered.

There are a variety of problems that can cause an error like this, and so we realize it is a problem that the error message doesn't provide more information. We are working on providing more error detail in these cases so you can take the right steps to correct it, but in the meantime users with access to Posit Support should feel free to reach out for assistance. Engineers can pull the logs for you as long as your attempt was within the last several days.
We've recently enhanced the product so that when an error occurs at this step, rsconnect will show you the root cause error that took place on our servers.
