While using switch_cros_cr_localbuild_master.py, it would have the following error

[stderr] Traceback (most recent call last):
[stderr]   File "./switch_cros_cr_localbuild_master.py", line 97, in <module>
[stderr]     main()
[stderr]   File "./switch_cros_cr_localbuild_master.py", line 82, in main
[stderr]     assert bisect_cr_localbuild_master.verify_gclient_dep(opts.chrome_root)
[stderr]   File "/usr/local/google/home/johnylin/chromiumos/src/platform/bisect-kit/bisect_cr_localbuild_master.py", line 95, in verify_gclient_dep
[stderr]     return solution['deps_file'] == '.DEPS.git'
[stderr] KeyError: 'deps_file'

The content of my .glcient file:

solutions = [
  {
    "url": "https://chromium.googlesource.com/chromium/src.git",
    "managed": False,
    "name": "src",
    "custom_deps": {},
  },
  {
    "name": "src-internal",
    "url": "https://chrome-internal.googlesource.com/chrome/src-internal.git",
    "deps_file": ".DEPS.git"
  },
]
target_os = ["chromeos"]

"src" doesn't have "deps_file" attribute, I think it has default value so actually the attribute is not there in the default .gclient file.
