Triggered an INTERNAL Error: BoundExpression::GetExpression called on empty bound expression

[tobilg]

What happens?

When trying to query a JSON file and unnesting its contents, I encountered the above error message:

select list_transform(unnest(Item), x -> unnest(x)) from 'https://gist.githubusercontent.com/tobilg/9d7cb9422f3d65fd93fca23e93cb22dc/raw/0df6fbeddad395fb67dc0eac9c87fab6d55e78a3/ddb_export.json';

Error message:
Error: INTERNAL Error: BoundExpression::GetExpression called on empty bound expression

After that, when I try to run another query in the CLI, e.g. select 1;, I see the following error:

Error: FATAL Error: Failed: database has been invalidated because of a previous fatal error. The database must be restarted prior to being used again.

and have to restart the CLI to continue.
