Updated version of the script. I think I will stop here

Hi George,

I am looking for device SDT which it can read devices from txt file. I tried to modify the above script and getting below error. Could you help me on it.

I am looking the solution to read the device names from txt file and making it in to sdt. Getting below output

I just realized I am not following my own post. What is the error message?

Since it has been a while and no response was given, if you are attempting to use device names from a list you need to specify the write property. The above code would return a bad JSON response.
