> We have a product type called CernerEvents. Some products of this type have values defined for met key "VpsEpisodeStartTime" and some products do not.
> When we run the query:
> {noformat}
> ./filemgr-client -u $FILEMGR_URL -op -sql -of '$VpsEpisodeStartTime' -q "SELECT VpsEpisodeStartTime FROM CernerEvents"
> {noformat}
> Then the following exception is seen (on XML-RPC server side):
