> Hi all,
> It seems like the python beam job I'm running is failing because of a bug in
> beam's metrics.
> The logic of the job appears to work and the final output is successfully
> being written on GCS, but the dataflow job throws and error and has a failed
> status:
> ```
> Traceback (most recent call last):
> File "path/to/my/code.py", line 11, in <module>
> MyJob().run()
> File "/path/to/my/lib.py", line 173, in run
> for c in result.metrics().query()["counters"]
> File
> "/usr/local/lib/python3.7/site-packages/apache_beam/runners/dataflow/dataflow_metrics.py",
> line 261, in query
> self._populate_metrics(response, metric_results, user_metrics=True)
> File
> "/usr/local/lib/python3.7/site-packages/apache_beam/runners/dataflow/dataflow_metrics.py",
> line 188, in _populate_metrics
> attempted = self._get_metric_value(metric['tentative'])
> File
> "/usr/local/lib/python3.7/site-packages/apache_beam/runners/dataflow/dataflow_metrics.py",
> line 224, in _get_metric_value
> lambda x: x.key == 'sum').value.double_value)
> TypeError: int() argument must be a string, a bytes-like object or a number,
> not 'NoneType'
> ```
> Note that prior to this stacktrace, there is a logging entry:
> ```
> {"severity": "INFO", "message": "Distribution metric sum value seems to have
> overflowed integer_value range, the correctness of sum or mean value may not
> be guaranteed: <JsonValue\\n object_value: <JsonObject\\n properties:
> [<Property\\n key: \'count\'\\n value: <JsonValue\\n integer_value: 96>>,
> <Property\\n key: \'mean\'\\n value: <JsonValue\\n integer_value: 0>>,
> <Property\\n key: \'max\'\\n value: <JsonValue\\n integer_value: 0>>,
> <Property\\n key: \'min\'\\n value: <JsonValue\\n integer_value: 0>>,
> <Property\\n key: \'sum\'\\n value: <JsonValue\\n integer_value: 0>>]>>"}
> ```
> I guess there seems to be an issue while casting the overflowing int to a
> double.
> (Note: We don't really have control over the number of events being fired
> since the metrics are emitted by `tensorflow_transform.beam.TransformDataset`)
