Store complex Provider Settings-value from Property Editor UI

[enkelmedia]

I'm working on a WorkflowType with a setting where I would like to reuse an existing PropertyEditorUI-component.

In older versions of Umbraco Forms I could send a JSON value to the server to be stored as a string-property.

I'm trying to get this to work on v15.0.3 and I'm getting this error when the properties are validated:

It's probably an error from the model binder, since the value is a object and not just a string.

I've tried a couple of things:

• To use the SupportsHtml-option but that did not work.
• Change the property from string to List<MyType> (the stored value is an array). Did not work but would be really cool if it was supported.

Is there a way around this or would I have to create propertyEditorUi specifically Umbraco Forms?

The docs indicates that this should work:

Each setting type can have it's own user interface. So a string can use a text box but a more complicated JSON structure can use a more appropriate user interface.

Maybe you could use JSON.stringify if the value is a object?

Cheers!
