Looks like the Clank bot auto-closed the tree due to failure of clang-clankium-tot-builder

https://ci.chromium.org/buildbot/internal.client.clank_tot/clang-clankium-tot-builder/

Failed build: https://ci.chromium.org/buildbot/internal.client.clank_tot/clang-clankium-tot-builder/62995

But I don't understand the error in the bottom of the build log
