I get the following output when I try to output some of my annotations:

```python
(env) [hadsed@hadsed-mbp-2 prodigy]$ pgy db-out goofy raw_datasets/
Traceback (most recent call last):

OSError: [Errno 22] Invalid argument

```

This doesn’t happen with the other annotations.

However, the command does work correctly on the machine that originally hosted the prodigy.db sqlite file. I copied it over to my personal machine and I get the above error. Perhaps the db was corrupted somehow?

It seems like the error occurs when the data is written to disk, so I don’t think there’s a problem with the database. (Just to be sure, you can always download the [SQLite browser](http://sqlitebrowser.org/) and have a look.)

Does the following alternative syntax work?

```bash
pgy db-out goofy > goofy.jsonl

```

Also, can you double-check that the directory path definitely exists and is writable?
