diRblo opened a new issue, #23090: URL: https://github.com/apache/beam/issues/23090
**What happened?** When I tried to read from a mongodb collection with only a single document in it, the worker returns "float division by zero" error. The source database is deployed in mongodb atlas and the pipeline is deployed on gcp dataflow runner. Below is the code we used and the error message got: **Code**: `pipeline | ReadFromMongoDB(uri=..., db=..., coll=..., bucket_auto=True)` **ERROR**: > Error message from worker: Traceback (most recent call last): > File "/usr/local/lib/python3.7/site-packages/dataflow_worker/batchworker.py", line 646, in do_work > work_executor.execute() > File "/usr/local/lib/python3.7/site-packages/dataflow_worker/executor.py", line 208, in execute > op.start() > File "dataflow_worker/native_operations.py", line 38, in dataflow_worker.native_operations.NativeReadOperation.start > File "dataflow_worker/native_operations.py", line 40, in dataflow_worker.native_operations.NativeReadOperation.start > File "dataflow_worker/native_operations.py", line 44, in dataflow_worker.native_operations.NativeReadOperation.start > File "dataflow_worker/native_operations.py", line 49, in dataflow_worker.native_operations.NativeReadOperation.start > File "/usr/local/lib/python3.7/site-packages/dataflow_worker/workercustomsources.py", line 112, in get_progress > fraction = self._range_tracker.fraction_consumed() > File "/usr/local/lib/python3.7/site-packages/apache_beam/io/range_trackers.py", line 286, in fraction_consumed > self._last_claim, self._start_position, self._stop_position) > File "/usr/local/lib/python3.7/site-packages/apache_beam/io/range_trackers.py", line 432, in position_to_fraction > return float(ikey - istart) / (iend - istart) > ZeroDivisionError: float division by zero -- This is an automated message from the Apache Git Service.
