  "message": "LogServlet: Handle HEAD symref to non-existent branch\n\nThe ObjectId of a Ref can be null. If HEAD is a symbolic ref to a\nnon-existent branch, headRef.getObjectId() will return null. The\ncurrent LogServlet code does not handle this, causing\nNullPointerException in RevWalk.\n\nThis issue is particularly common when a repo is created but nothing is\npushed yet; so a HEAD symmetry is created to point to refs/heads/main by default but lacks a commit SHA.\n\nTreat a HEAD ref with a null ObjectId as if the ref itself were null,\nreturning no view instead of throwing an internal error.\n\nChange-Id: I4fe85010db0694403770923fcdf957854e72cd34\nSigned-off-by: Xing Huang \u003cxingkhuang@google.com\u003e\n",
