error codes

Question

hi...I keep getting "error code 124".  What is this error?  And is there a list of the 3-digit RM error codes?

Thanks.

Hi,

Execute Program will usually try to relay the OS error code of your command.

thanks for the link.  That's very helpful.  Unfortunately that message seems weird.  What I have is an Execute Program operator inside a loop where it executes a shell script with different variables every time.  Sort of like this:

file_name macros inside loop:

Scott.txt

Bob.txt

Eric.txt

Mary.txt

etc...

Execute Program

cat %{file_name}

Then I pull the output and do some work on it.  I'm not actually using cat...it's just an example.

Normally this works fine but every once in a while I get this error 124.  Maybe it's character length or a weird character?  I will see next time it happens.

And any thoughts on how to timeout if the shell script will not terminate?  I tried the Unix "timeout 1 cat %{file_name}" but RapidMiner does not like it for some reason...

Thanks.

Hey Scott,

learning something new every day :)  124 is:

error.124.name  = Wrong process setup
error.124.short = The operator cannot handle more than {1} input objects of type {0}.
error.124.long  = Each operator defines which input is desired for applying this operator (these input objects are shown in operator info screen (F1)). Previous operators must load or produce the desired input objects. You can check the correct process setup by validating the process (via the icon or the menu item).

All messages are defined here: https://github.com/rapidminer/rapidminer-studio/blob/4759926c6cf845c42b961ef3faff2442a26662ca/src/main/resources/com/rapidminer/resources/i18n/UserErrorMessages.properties
