Upper & Lower functions do not work

[Vineet_Kakroo]

Hello All, anyone else facing similar issue.
Whenever I use Upper or Lower functions to convert text to upper/lower, it does not work and my flow crashes and call disconnects and as soon as I remove these functions, flow works.
A simple example, variable X = "Hello" and using Upper(Task.X) fails and call disconnects, and same with Lower(Task.X).
And the failure happen even if i use these functions in a Condition or Switch or UpdateData actions.

I am hoping someone else may have had similar experience and may have a way around it. I will raise a support ticket anyway.

Hello,

I've tried reproducing this issue and so far I've been unsuccessful. But I think you've taken the correct approach and opened a support ticket.

Are you sure that Task.X has a value at the step you are using Upper/Lower/etc? In this example the update data in the no path will fail b/c Task.X does not have a value. You can check to see if a variable has a value using the IsSet or IsNotSetOrEmpty functions.

Hi Melissa/Kevin,
Apologies for not replying earlier. I was away on a break.

In my scenario, that data is coming from a Data Table and yes some of the fields can be blank. I am sure I tried to use the function to check isnotsetorempty but it still did not work. I will try it out again.
