Result is wrong when output is more than 10,000 lines

I have got a deployment instrument output with 12,224 lines. So circleci browser doesn’t display the entire output and shows “Your build output is too large to display in the browser. Only the first 400000 characters are displayed.
Download the full output as a file.”

Unfortunately there’s a python traceback (timed out when install requirements) starts at line 11,957,followed with some other errors caused by it.

Circleci doesn’t realize this and gives a build result “Success”, which should be “Failed” actually.

Update: tried for a second time,got a different error. But result was still “Success”.
