Price Check Test Header Issue in Developer Document

Hi Team,

My partner reported the test header enums on developer doc are inaccurate. It listed "matched", but when using "matched" test header, our API throws out the error: "Content of the test header is invalid. Please use one of the following valid values: available, price_changed, service_unavailable, sold_out, unknown_internal_error". I can reproduce it as well:


Please help to check and correct the document if needed. Thanks 

Best,
Luna Zhang?
