    HI
     
    You need to share the Data of the Run. Your flow looks like, but your data is clearly NOT good.
     
    Open the run that failed, look at the value it received for whatever property you are looking at. Its NOT in a format that formatDateTime can parse and thats why you got the error
     
    Show you code expression as well. There isn't anything we can do since you aren't showing us the error, in a run and showing the data and expressions.

    Hi FLMike and Chriddle
     
    It turned out that the -MM- in my date format was in lowercase instead of upper case.
     
    I changed it to 'yyyy-MM-dd' then it worked.
     
    Thank you for all your trouble.
     
    Cheers
