crash on home page when project not running

[haraldschilly]

Opened a sagews file as a "normal user", project wasn't running, and when opening the "home page" of the project, I saw this stack trace.

The part in the code is here, pointy brackets indicate the location.

        function u(e) {
            var t = !0
              , n = !1
              , r = void 0;
            try {
                for (var i, o = e[Symbol.iterator](); !(t = (i = o.next()).done); t = !0) {
                    var a = i.value;
                    a.content && a.content.includes(s) && (a.content = a.content.replace(c, ""),
                    null != a.children && u(a.children))
                }
            } catch (e) {
                n = !0,
                r = e
            } finally {
                try {
                    t || null == o.return || o.return()
                } finally {
                    if (n)
                        throw r
                }
            }
        }
        function d(e, t) {
            var n = void 0;
            if (e = function(e) {
                return e.replace(/^(```+)\s+$/gm, "$1") <<<<<<<<<<<<<<<<<<<<<<<<<<<<<
            }(e),
            !t) {
                var i = (0,
                r.parseHeader)(e);
                e = i.body,
                n = i.header
            }
            var o = e.split("\n");
            e = function(e) {
                return e.replace(/(?:\S)\ $/gm, (function(e) {
                    return e[0] + l
                }
                ))
            }(e);
            var a = {}
              , s = r.markdown_it.parse(e, a);
            return u(s),
            {
                tokens: s,
                meta: n,
                lines: o,
                references: a.references
            }
        }

Ohh, I got it, this happens when you try to open a file of another user, where you do not have access. Well, the take away is the UI should clearly say to the user, that he or she has no access ... instead of crashing in weird ways.

Coincidentally, I just fixed an issue that probably led to you getting into a situation where this (="open a file of another user, where you do not have access.") could happen: https://github.com/sagemathinc/cocalc/commit/498e14a067768d12acfe295f8e76875a08b08ffa
