dbt 0.19.1 - missing field in dbt.adapters.sqlite.connections.SQLiteCredentials

[robastel]

Firstly, thank you for building and releasing dbt-sqlite. I find it really useful!

With dbt-sqlite==0.1.0 and dbt==0.19.1, I am encountering the following error when running dbt compile:

Running with dbt=0.19.1
Encountered an error:
Field "extensions" of type typing.Union[str, NoneType] is missing in dbt.adapters.sqlite.connections.SQLiteCredentials instance

Previously, with dbt==0.19.0, everything was running smoothly for me.

I took another look at the dbt-sqlite README.md section on how to set up profiles.yml. This part in particular:

# optional: semi-colon separated list of file paths for SQLite extensions to load.
# digest.so is needed to provide for snapshots to work; see README
extensions: "/path/to/sqlite-digest/digest.so"

The error message I encountered leads me to consider that maybe extensions is no longer optional in dbt==0.19.1.

I was able to get around the error by following the idea of this comment in the dbt Slack group: https://getdbt.slack.com/archives/CJN7XRF1B/p1618594722275700?thread_ts=1618545451.270400&cid=CJN7XRF1B

For me it looks like:

extensions: "{{ 'None' | as_native }}"

Doing that eliminated the error for me and didn't seem to break anything with dbt-sqlite 0.18.x or 0.19.0.

There might be a simpler solution. I don't know enough about extensions to know. I just wanted to call it to your attention.

Hey, thanks for using this adapter and for reporting this!

I think dbt 0.19.0 should also have been complaining about this, not sure why it wasn't, I've committed a fix and released 0.1.1 on PyPI. With that new version, you should be able to omit 'extensions' completely if you don't want to set the value for it.

Thanks for the quick response! I am able to successfully omit 'extensions' again as you said.
