We are using the latest arangodb version (official docker image for arangodb) and we are getting following error:

This is simple info taken from arangodb dashboards:

@sudeepvd we tried some of the forks of arangochair because this repo is dead. And fortunately the layro01/arangochair's fork worked. You can use it in your package.json as follows:

"dependencies": {
    "arangochair": "layro01/arangochair"

I dont know why the owner of the repo ignores PR and issues but at least we have the working fork. plz let me know if this helped.

@VladoDemcak : It worked. Thanks for your quick turnaround.
