`Undefined index: sid` when getting FoldingAtHome stats

[serge1peshcoff]

When I add FoldingAtHome and either try to test it on the app editing page by pressing the "Edit" button or loading the dashboard when it's saved, I'm getting the 500 Internal Server error with the following content:

Endpoint: GET http://<ip:host>//get_stats/6

Do you know what can cause it and how can I fix it?

I'm using Heimdall v2.2.2 inside Docker, if that can help.

from what I understand, the php script fetches js/main.js of the FAH url, then tries to find a string like sid = '123', which isn't there, as apparently js/main.js does not contain this string anymore. instead, it fetches it from the backend:

$(function () {
  $.ajax({method: 'PUT', url: '/api/session?_=' + Math.random()}).done(main)
});

and then calls it with this sid argument:

function main(sid) {
  fah.sid = sid;

// more follows

and this endpoint queried indeed returns a hex string, which apparently is sid
