Error Date Field creating CSV

(0) ShareShare

Posted on by DLCaterhamSch 394 Super User 2024 Season 1

Dear All,

 

I have two date fields in a create CSV and one works and one not. 

 

Error is:

The column values could not be evaluated: 'The template language function 'formatDateTime' expects its first parameter to be of type string. The provided value is of type 'Null'.

 

The formula which works for date columns is formatDateTime(item()?['Date'],'dd-MM-yyyy') however using it on another column just created errors.

 

Any help is appreciated.

 

Daniel

    Some date values in your dataset must be empty. You can run a null check before using formatDateTime. Try

     

    if(empty(item()?['Date']),null,formatDateTime(item()?['Date'],'dd-MM-yyyy'))

    You are right, just checked and one entry is null. Thank you.
