Getting Error while using the update Constant Smart Service

Question

I have a requirement needs to update multiple constants with corresponding values. I have a constructive data type which will have the constant name in text and corresponding value. I am using update constant smart service to update the constant. Since i have multiple constants i have configured MNI to the smart service. while running the smart service i am getting the error " The constant specified is invalid or does not exist. Constant ID: null." 
 Thanks in advance for the suggestions

How do you get the name of the constants you are going to update? Maybe one of them is null?

I just checked the smart service. The problem is, that you cannot just pass the name of that constant, but you need a reference to the constant. Or, the content ID. 
 Using the content tools plugin, I came up with this: 
 tointeger(split(getcontentdetailsbyuuid(getconstantorruleuuidbyname("SSH_UPDATE_TEST")), ",")[2]) 
 Please test and verify this code to make sure it works for your situation!

You will have to make sure to only call that smart service if the name is not null.
