We've upgraded our Umbraco site from version 7.7.4 to 7.11.1. All works locally, but when deploying to any other environment, we get the error message below when trying to edit/specify the property type of any doc type property. Wondering if anyone else has seen this issue, or might have a suggestion as to what the problem / fix is?
Source value:
Umbraco.Core.Models.DataTypeDefinition ---> System.InvalidOperationException: Sequence contains more than one matching element
at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable1 source, Func2 predicate)
at Umbraco.Core.PropertyEditors.PropertyEditorResolver.GetByAlias(String alias)
at Umbraco.Web.Models.Mapping.DataTypeModelMapper.<>c.
We managed to fix this in the end. It was down to the way we were deploying to the environment - the target folder wasn't properly being cleared down before deployment, which looks like what caused the type to be registered twice.
