When using source.read() getting an error: "getCursorField() is null"

## Code example:
```python
# Set up the source
source = ab.get_source('source-redshift')
source.set_config(config=config)
source.select_streams(tables)

# Read data from the selected stream
read_result = source.read()
```

## Getting the following error:
`java.lang.NullPointerException: Cannot invoke "java.util.List.size()" because the return value of "io.airbyte.protocol.models.v0.ConfiguredAirbyteStream.getCursorField()" is null`

### Full stacktrace:

## Workaround
When using `get_records` it works:
```
read_result = source.get_records(stream=table)
```

Is there a workaround to avoid using the cursor field in this case?
