I get an error when trying to rebuild the examine index (umbraco 12) this is a new issue from upgrading from 8 to 12. Any advice in solving? Error message: Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Umbraco.Cms.Core.Models.Blocks.BlockValue' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.

Did you find a solution for this? I have the issue with some notes while i'm converting the nestedcontent to blocklist. I can't save the nodes without getting this error. Put if I have and publish, then it works fine, also the save afterwards..
