-16069 A REGULAR EXPRESSION ARGUMENT value PASSED TO THE FUNCTION function-name MATCHES A ZERO-LENGTH STRING. ERROR QNAME= err:FORX0003
Explanation
The value that was specified for the pattern parameter in a call to the function function-name matches a zero-length string. A zero-length string is not a valid pattern for this function because the pattern will never match a substring in the input string.
Programmer response
Pass a valid pattern to the function call, or remove the function call from the expression.
