As of Tuesday, the Lichess explorer API (which is optionally used by Nibbler) requires an authentication token.
As a temporary solution, Nibbler 2.5.4 can read a token which is stored in Nibbler's config.json (which you can find via the Dev menu) as the property lichess_token.
To get such a token:
- Login to Lichess at https://lichess.org/login
- Then go to https://lichess.org/account/oauth/token/create
- Create a token there. You do not need to tick any of the boxes, just scroll down and click
Create. - Quit Nibbler if you happen to have it running.
- Now edit Nibbler's
config.jsonfile and find the line"lichess_token": "", - Insert your token inside the quotation marks. Do not delete the quotation marks. Do not delete the trailing comma.
- So now it should look like:
"lichess_token": "lip_12345",or whatever.
Perhaps I will make a more elegant solution at some point.
