I'm also hitting the "This value should be of the correct primitive type" error with float configs, when I refactor the form to use the shiny new-ish #config_target functionality, and submit the form with blank/empty number form fields, which previously worked fine for submitting NULL values.

I did add nullable: true to the config schema, but still get the same error when I submit the config form. I guess either PrimitiveTypeConstraintValidator should be made aware that the value is nullable and therefore empty string should be cast to NULL, or I need a way to disable/override this validator?

...well what I ended up doing, to allow submitting empty string to a nullable float, was use a ConfigTarget callback to convert empty string to NULL (passing through any other string), and that seems to work fine.

I haven't run into this on D11, but several times on D10.

As a work around, in propertyDefinitions() create the property as $type = 'any'.
e.g.
$properties['item'] = DataDefinition::create('any')
->setLabel(t('Item Label'))
->setDescription(t('... Item description ...'));

Then in schema() you can set your data type to what you need, instead of doing what mfb had to do.

You can also user massageFormvalues() to set empty strings to null, which is the approach I took in a custom widget.
