Hi John, have you looked at the values in your `table`? Do any of them
contain the value `[\n"partition1"\n]`?
I tried to reproduce this (just locally, not GCS yet), but was not able to
(writing the dataset worked fine):
```python
import pyarrow as pa
import pyarrow.dataset as ds
table = pa.table(
{
"partition1": ["1", "2", "3", "4", "5"],
"partition2": ["2001", "2002", "2003", "2004", "2004"],
"3": ["1", "2", "3", "4", "5"],
"val": list(range(5)),
}
)
file_options = ds.ParquetFileFormat().make_write_options(compression="zstd")
partitions = ds.partitioning(
schema=pa.schema(
[
("partition1", pa.large_string()),
("partition2", pa.large_string()),
("3", pa.large_string()),
]
)
)
ds.write_dataset(
table,
f"tables/test_parts",
format="parquet",
file_options=file_options,
partitioning=partitions,
schema=table.schema,
existing_data_behavior="overwrite_or_ignore",
)
```
