Where are you seeing this error?

It looks like that bot was renamed android_webview_aosp_perf_bisect -> android_webview_arm64_aosp_perf_bisect back in June: https://codereview.chromium.org/2088033002/

Whoops, pasted this on the wrong bug, was comparing this "successful" output with an unsuccessful one at bug 673325. Sorry for the confusing comment! Will move that discussion to bug 673325.
