Error Message :
U00020308 Runtime error in object 'JOBS.WIN.INC00124939', line '00004'. Invalid internal parameter type '010121'.

In Automation Engine (AE) version 11 and 12, script function :REGISTER_VARIABLE returns an unexplicit error message "Invalid internal parameter type '<number>'" in the "Messages" window when the second parameter is missing.

Example:
 

This behavior only impacts AE versions 11 and 12.

Investigation

The error can be seen in jobs where a parameter of :REGISTER_OUTPUTFILE is missing. Here is an example:

dir C:\temp /S >> C:\temp\[email protected] retcode=%errorlevel% [email protected] NOT %ERRORLEVEL% == 0 goto :retcode:REGISTER_OUTPUTFILE "C:\temp\test.txt"

There is an error because :REGISTER_OUPUTFILE should always be used with the following syntax:

:REGISTER_OUTPUTFILE File, User Login

The correct usage of this script function should be:

:REGISTER_OUTPUTFILE "C:\temp\test.txt", "Y"

 

Cause type:
Defect
Root Cause: When :REGISTER_OUTPUTFILE is used without any parameters, a misleading error is displayed. This results in: U00020308 Runtime error in object 'JOBS.WIN.1', line '00004'. Invalid internal parameter type '010121'.
