and when i tried to use the debugger-ui only it doesn't work aswell and showing me this error:

Development Tools failed to load source map: Unable to load content from http: // localhost: 19000 / debugger-ui / debuggerWorker.aca173c4.js.map: Failed to retrieve via target: Target not taken in charge ; Fallback: HTTP error: status code 404, net :: ERR_HTTP_RESPONSE_CODE_FAILURE

i even created a blank project to test if the problem is caused by my project but it didn't work aswell showing me the same errors.

Any help would me much appreciated.

I ran into a similar problem. I discovered the react-native-debugger was opening an instance in my web-browser and a separate stand alone instance. When I closed the instance in my web browser, the error stopped occurring and I could debug normally. – Ozonize

I also had this problem, my dependencies:

...
"expo": "~43.0.0",
"react": "17.0.2",
"react-native": "0.66.3"

Seems like "react-devtools-core" in react-native dependencies install old package version.

I added

  "resolutions": {
    "react-devtools-core": "4.14.0"
  }

To package.json for solving this problem. I also reinstall last react-native-debugger ( brew reinstall react-native-debugger) Maybe it will help you.

Thank you for you response, but sadly it didn't work for me and the react-native-debugger still showing the same error. – Nessim

you need to add the dependency and install the package again with npm or yarn. Worked for me well! – Intangible
