[BEAM-11604](https://issues.apache.org/jira/browse/BEAM-11604)
I tried to the example streaming_wordcap/wordcap.go and panic occurred.
```
$ cd beam/sdks/go/examples/streaming_wordcap/wordcap.go
$ go run wordcap.go \
--project=MY_PROJECT\
--temp_location=gs://MY_BUKET/tmp\
--staging_location=gs://MY_BUKET/binaries\
--runner=dataflow

I prevent panic by fixing translate.go.
```
$ go run wordcap.go \
