# 60617: Lookup Not Enough Request Parameters

Log Type: APPLICATION

Log Level: ERROR

## Description

Missing at least one valid additional argument to execute the Lookup you requested

### Possible causes

The request was received but failed due to the Lookup package you requested requiring at least one optional request parameter to match against the phone number. If there is a single request parameter, its value may not be left blank.

### Possible solutions

* Review request parameters to ensure at least one optional field, such as FirstName, is included.
