 * Hi,
 * When I open Swaggerfor a WordPress/WooCommerce site I get an error at the end
   of the page:
 * {“schemaValidationMessages”:[{“level”:”error”,”domain”:”validation”,”keyword”:”
   oneOf”,”message”:”instance failed to match exactly one schema (matched 0 out 
   of 2)”,”schema”:{“loadingURI”:”[http://swagger.io/v2/schema.json#&#8221](http://swagger.io/v2/schema.json#&#8221);,”
   pointer”:”/definitions/parametersList/items”},”instance”:{“pointer”:”/paths/~
   1wc~1v3~1coupons/post/parameters/19″}}]}
 * The last METHOD that shows correctly is:
 * data
    … /wc/v3/data/currencies/{currency}
 * Any idea what coud be the cause ?
    I have tested in 2 different sites and the
   error is the same.
 * Thanks
