So am getting this error on importing a Content Picker, I have not sync Content yet so might be that? On importing I am getting the following on Content pickers (maybe others but figure once I know how to fix one I can fix em all) "DataTypeHandler": Import Failed : "System.ArgumentNullException: Value cannot be null. (Parameter 'value') at Umbraco.Cms.Core.Models.DataType.set_Configuration(Object value) at uSync.Core.Serialization.Serializers.DataTypeSerializer.DeserializeConfiguration(IDataType item, XElement node) at uSync.Core.Serialization.Serializers.DataTypeSerializer.DeserializeCore(XElement node, SyncSerializerOptions options) at uSync.Core.Serialization.SyncSerializerRoot1.Deserialize(XElement node, SyncSerializerOptions options) at uSync.BackOffice.SyncHandlers.SyncHandlerRoot2.ImportElement(XElement node, String filename, HandlerSettings settings, uSyncImportOptions options)"

Hi, Importing the content shoudln't actually matter ,the IDs are not checked when the config is saved in umbraco. I've just check that config above (i pasted it into my own migrtation and ran the import) and it seems fine. is that the migrated config (from a "Migrations/something" folder)?

Yeah

OK, so that looks broken . It reporting that it can't find the core datatypes. 😟

Classic me problems 😄

What version of Umbraco is that on ?

10.6.1

i think your datatypes aren't synced / converted.

So If I fix my custom property and do another zip upload?

yeah - i think you need to make sure you have the datatypes folder in there

Ok so Ill add the package.manifest and set up the v8 _site in the uSync folder

If its a datatype you want to exist on the new site, then the app_plugins in the actual site will need to be where they go. (the conversion doesn't care to much if the datatype exists or not, its the subsequent import where its asking the current umbraco site to setup the new datatype that matters)

So I have a blank data base custom data types are defined via a package.manifest in 7/8/10 just copied it over same for the grid.editor.js

yes - the migration packers can actually do some of this for you (see https://github.com/Jumoo/uSyncMigrations/blob/main/GETTING-STARTED.md) they mainly they make a merged grid.editor.config.js file from all loaded configs. but copying over the stuff to app_plugins and grid.editor.config.js does do the same thing.

it errored when I tried uploading the zip 🙂

😦 - i suspect there is something odd going on with encoding - what error did you get.

Finding out now

😄 - i mean your not the only one, the UI might need polish

with the zip 😦

is the zip massive ? coudl you email me it and i will quickly see what happens when i have a go ?

33MB ill upload it and share it with you on sharepoint 🙂

So presumably. the error is a datatype handler error. ?

Could I have the database 😄

it was a fresh v10 install. admititly using SQLite

I guess Ill try again with a fresh database
