   @nicknezis  Thanks
   
   There seems to be a case where the object temporarily does not exist at the time of update.
   So I added it to check whether the object exists.
   
   
   And I executed the component as below.
   # Tracker
   ```
   bazel build heron/tools/tracker/src/python:heron-tracker && bazel-bin/heron/tools/tracker/src/python/heron-tracker --config-file ~/.heron/conf/heron_tracker.yaml --verbose
   ```
   # HeronUI
   ```
   ln -sf ~/.heron/release.yaml /private/var/tmp/_bazel_thinker0/1db3221e319a1f6b3420bd0c6f4d8d08/execroot/org_apache_heron/bazel-out/darwin-fastbuild/bin/heron/tools/ui/src/release.yaml
   
   bazel build heron/tools/ui/src/python:heron-ui --verbose_failures && ./bazel-bin/heron/tools/ui/src/python/heron-ui --tracker-url http://localhost:8888
   ```
