I'm trying to create a simple view in AWS Athena, and then query that view. The initial query runs fine, and returns results. Then, I click "Create view from query", and it runs the following, which also is successful:
CREATE OR REPLACE VIEW "ios_events" AS
SELECT *
FROM my_db
WHERE context.device.type = 'ios';
However, I cannot query this created view at all. it shows up in the UI, but even when I click "Preview" for the view in the UI and it runs:
SELECT * FROM "my_db"."ios_events" limit 10;
This results in a large error starting with GENERIC_INTERNAL_ERROR: Unable to create class com.facebook.presto.execution.TaskInfo from JSON response:. Later in the error, it has the following:

Which seems to imply the query is not structured properly. But this is just a super simple select, generated by the AWS Athena UI itself. What am I missing?
