api-docs on Swagger UI error

The link on the Swagger UI for api-docs, shows Error - {"schemaValidationMessages":[

{"level":"error","message":"Can't read from file http://127.0.0.1:8080/RestVDB/api-docs/Debbiev"}

]}

But I can enter the URL and go to the api-doc - http://127.0.0.1:8080/RestVDB/api-docs/Debbiev
