I've followed the steps @ https://our.umbraco.org/documentation/Umbraco-Cloud/Deployment/Migrate-Existing-Site/

However when I commit and push to the cloud I get the following error. It fails to build the document & media types as a result which means the schema is out of sync and I can't move forward in the deployment.

The exist site has Umbraco Forms installed along with a number of other third party applications but I hoping it's something more simple than an issue with a third party package.

Anyone with any ideas?
