Splunk DB Connect 2: Why am I getting error "[name of my indexer] Script for lookup table 'mylookup' returned error code 1. Results may be incorrect"?

Hey I am receiving the following error when attempting to run my database lookup using DB Connect 2: [name of my indexer] Script for lookup table 'mylookup' returned error code 1. Results may be incorrect I am running the following when doing a search index="index i am searching" | lookup mylookup userOId AS UserOId OUTPUTNEW firstName lastName The lookup is supposed to correlate json events using the userOid with the firstname and lastname located in a MSSQL database Any suggestions on where I should look for more information on this error? I don't see anything in the Splunk logs.
