Description
When sending a GET request to the test-tool device with, for example, the 'toaster2' model, it responds with a 500 error when asked for the 'Accept: application/yang' header.
The same request but with "Accept: application/yin+xml" header is working.
- Sending application/yang headers is working for controller models.
- In Karaf logs, there are no errors.
- Creating SchemaExportContext is successful for the device model. The exception is thrown in YangSchemaExportBodyWriter with the message: "Unable to retrieve source from SourceProvider."

The issue arises from the invocation of context.sourceProvider() within the YangSchemaExportBodyWriter class. This DOMYangTextSourceProvider contains controller models. Probably it will be required to explore alternative methods for generating the YangTextSchemaSource. For example, as it is done in
YinSchemaExportBodyWriter.
