Hi,
Without seeing the UDA its hard to say what the exact cause is but on the face of it the UDA outputs a number but it appears that a different data type is being passed to the output and its not compatible.
This could be a string being passed to the output for instance.

Thank you so much there were null values that for some reason needed the information, I think thats what caused the error, after asking the user to enter the information needed and restart the workflow, everything worked ok, thanks a lot for the reply it helped.
