Error: Swagger schema's not supported

[khareyash05]

Hi! When I am trying to parse a swagger schema file m giving me this error

value of openapi must be a non empty string

this is a small snippet of my code

ctx := context.Background()
	loader := &openapi3.Loader{Context: ctx, IsExternalRefsAllowed: true}
	doc, err := loader.LoadFromFile(filePath)
	if err != nil {
		return nil, fmt.Errorf("failed to Load OpenAPISchema file: %w", err)
	}
	err = doc.Validate(ctx)
