```
Unexpected error: user-defined function raised exception
```

As mentioned in https://code.djangoproject.com/ticket/29500 and https://stackoverflow.com/questions/45824209/how-to-get-an-error-kind-from-sqlite-create-function/45834923#45834923 the workaround for this is to enable callback tracebacks:

```
sqlite3.enable_callback_tracebacks(True)
```

It would be nice if https://sqlite-utils.datasette.io/en/stable/python-api.html#registering-custom-sql-functions either included a reference to `enable_callback_tracebacks` or if registering a user defined function set this flag automatically.",140912432,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/300/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed
