This happens when the developer has not entered the CLIENT_ID or CLIENT_SECRET, in the required place. Do refer the README.md, for storing the keys.
Possible Solutions:
- Store the keys in their respective place, as mentioned in the README.md.
- If you have stored the keys, and the error still persists, try opening the tool, on the icongnito mode.
- This can also happen when you have some extensions in your browser (Ex: MetaMask), which clears up your localstorage of the browser, and so the keys are not passed to the client.
Do check your localstorage, for these keys.
