   • Confirm that the "link" field type has the "URL for link (link field only)" enhancer applied to it.
   • "Get Absolute Urls" should be unchecked.
2. Navigate to "/jsonapi/paragraph/react_widget/5663a0dd-a69c-40b7-b50b-526646e32204"
   • Validate that field_default_link has a relative url with a value similar to the uri field's value.
3. Navigate to "/admin/config/services/jsonapi/field_types", check the "Get Absolute Urls" setting, and save the form.
4. Navigate to "/jsonapi/paragraph/react_widget/5663a0dd-a69c-40b7-b50b-526646e32204"

5. Edit "/admin/config/services/jsonapi/add/resource_types/paragraph/react_widget" to add the "URL for link (link field only)" enhancer to the "field_default_link" field. Make sure to uncheck "Get Absolute Urls".

checked:

unchecked:

can still be overridden at a field level per resource type:

[tjheffner]

this .gitignore part of the patch, is that just in the module?

also fine with a local patch here, but i think it's probably worthwhile to add it to d.o and reference it that way

[alexfinnarn]

yes, this is in the d.o. issue MR and patch.
