end of the stream or a document separator is expected in "http://localhost:3000/example.yaml" (36:47)

Question

I am getting the error above and I saw plentry of similar post and they said it was a formatting issue with the yaml file. But I am using redocly cli to validate the yaml file by running redocly lint example.yaml and it returns Woohoo! Your OpenAPI definition is valid. I am using the following method to consume the yaml file RedocStandalone specUrl="./example.yaml" . I am not sure why I am still getting the above error
