Major - P3 assert.commandWorkedOrFailedWithCode = function commandWorkedOrFailedWithCode(res, errorCodeSet, msg) { if (!res.ok) { return assert.commandFailedWithCode(res, errorCodeSet, msg); } else { return assert.commandWorked(res, msg); } };
But not all operations, such as insert, have the 'ok' field in the response. For those operations the commandFailedWithCode branch is always taken.
Possible fix:
assert.commandWorkedOrFailedWithCode = function commandWorkedOrFailedWithCode(res, errorCodeSet, msg) { try { return assert.commandWorked(res, msg); } catch (e) { return assert.commandFailedWithCode(res, errorCodeSet, msg); } };
