Error at pushing / pulling in Umbraco 15.2.2 - uSync Complete 15.1.3

[grufian]

Describe the bug
We use Azure Web Apps to locate our Umbraco web apps.
We tried to sync (with uSync Complete) some content from a local environment (located in an IIS Express) to a webapp in Azure.
It throws a "Remote Error".
Checking the Umbraco logs, it throws a "System.NotSupportedException: The converter for derived type 'System.Collections.IDictionary' does not support metadata writes or reads.", no matter if it's a pull or a push operation in a node.

To Reproduce
Steps to reproduce the behavior:

1. Go to any node in a local Umbraco
2. Click on Pull / Push.
3. Select a server located in Azure.
4. Doesn't matter whether I include children or not.
5. It throws an error.

Expected behavior
I can sync to an Umbraco located in an Azure Web App.

Hi,

Can you perform a full export using usync's standard dashboard, and see if you get any errors, also if possible can you perform a uSync.Export of the site to a syncpack file ?

if that does work it would be great if you could send us the syncpack file and we could test locally (kevin@jumoo.co.uk).

I suspect its a configuration element inside some bit of content/data type. but we would need to see what it might be to dig into it.
