swagger ui "try it out" problem again

[blatoo]

I can not use "preview mode" in vscode the "try it out" function:

I simply want run: http://localhost:9000/todos , but it always return: TypeError: Failed to fetch, however, when I use my webbrowser, it works totally fine.

Here is my swagger.yml file:

openapi: '3.0.2'
info:
  title: API Title
  version: '1.0'
servers:
  - url: 'http://localhost:9000'
paths:
  /todos:
    get:
      responses:
        '200':
          description: OK!

Actually I saw the same question in a previous thread, but @vfateev said it was solved:
#80

But, it doesn't looks like solved in version 3.8.0 ....

Could you try opening developer tools panel as described here https://code.visualstudio.com/api/extension-guides/webview#inspecting-and-debugging-webviews and inspecting the error messages on the console of the devtools?

It would be helpful if you could provide more detailed error message then the one shown by Swagger UI

@ak1394 Thanks very much for the help. The problem suddenly disappeared, after I open the devtool. I have no idea, why this happens, but I guess, may be cache...
