DBConnect Query Failing After Upgrade

[sarge338]

I have a DBConnect query that runs to populate the panel of a dashboard every week.  We upgraded both the database which houses the data AND Splunk a couple of weeks ago.  The new database is Postgres 14 and Spunk is not at 9.2.3.  I have run this query directly on the Postgres box, so it appears that Postgres doesn't suddenly have an issue with it.

Other panels/queries in this dashboard use the same DBConnect connection, so the path, structure, and data all appear to be good.  The issue seems to lie with the "math" in the time range, but I cannot put my finger on why.  Basically, we are trying to pull a trend of data going back 8 weeks, starting from last week.

query=" SELECT datekey, policydisposition, count(guid) as events
FROM event_cdr
WHERE datekey >= CURRENT_DATE - CAST(EXTRACT(DOW FROM CURRENT_DATE) as int) - (7*8) AND
               datekey < CURRENT_DATE - CAST(EXTRACT(DOW FROM CURRENT_DATE) as int) AND
direction_flag = 1 AND
policydisposition = 1
GROUP BY
    datekey, policydisposition
ORDER BY
   datekey, policydisposition 

When I try to execute this query, I consistently get the following error:
"Error in 'dbxquery' command: External search command exited unexpectedly.

The search job has failed due to an error. You may be able view the job in the Job Inspector"

Some of the search.log file is here:

Some additional information that was somehow omitted from my original post....

If I change date range part of the query from "(7 * 8)" to just "7".  The query runs fine.  If I change "(7 * 8)" to "(7 * 1)", the query runs fine.  If I change "(7 * 8)" to "(7 * 2)"... or any number greater than 2... the query fails with the same error as mentioned in the original post.
