Server crashes.

Patterns file is from [prodigy-recipes](https://github.com/explosion/prodigy-recipes)/[example-patterns](https://github.com/explosion/prodigy-recipes/tree/master/example-patterns)/ **patterns\_drugs-DRUG.jsonl**

Server launches properly WITHOUT the --patterns argument.

Happy to supply more data as you request. Hope you find it to be my cockpit error.

Thank you.

Thanks for the report – and sorry about that! The pattern matcher writes the matched pattern info to the task's `"meta"` so it's displayed in the bottom right corner of the annotation part. And it didn't correctly make sure the dict is created if it doesn't exist. I've already fixed this internally and we'll push another patch release with the fix.

In the meantime, the easiest workaround would be to add `"meta": {}` to each example:

```python
import srsly
examples = srsly.read_jsonl("./notes.jsonl")
for eg in examples:
    eg["meta"] = {}
srsly.write_jsonl("./notes_updated.jsonl")

```

**Edit:** Just released v1.9.2, which fixes the underlying problem 🙂

Thank you kindly, Ines! 1.92 Installed in a few seconds. **new.manual . . . --patterns** now works per the new docs.
