SetParameter error: TypeError: Multiple targets could match: Set(str), Set(ElementId)

[DanTheMan]

Hey everyone,

I have the task to set project paramters for the current Document.
What i did so far:

1. Get the informations i need in 3 Lists

   • one list contains the elementID
   • one list contains the parameters i want to set
   • one list with the parameter values

2. wrote a script that writes the parameter values in the right paramters to the right element. If i execute the script i get an error which said: “TypeError: Multiple targets could match: Set(str), Set(ElementId)”

I have no clue why i am getting this error because i used same script and it worked fine:

What it’s telling you is that one or more of your elements has a Parameter by the name your looking up that wants an ElementId as the value and not a string.

Check to make sure all of your elements have the Parameter with param type Text.

Hello @DanTheMan
in addition to @SeanP 's answer it will seem that you have null values in your Parameter values list

thanks so much

String from Object did the trick

I feel bad for opening the topic a again. @c.poupin @SeanP

I worked on the script and after executing the script i got an error:

Warnung:IronPythonEvaluator.EvaluateIronPythonScript fehlgeschlagen.
Traceback (most recent call last):
File “”, line 38, in
AttributeError: ‘NoneType’ object has no attribute ‘Set’

It sets the Parameter for the first Element in the list and then i get this error

can someone help again?
