Posted on by 67

Hey Community,

 

i have a Flow which cycles through a get listitems and updates those listeitems.
Problem is that i have a date column which shall be set to null in the update items action.
Normally, what i found in the Forums and Copilot :), setting the Date column to null should do the job

    Hi @MB29 ,

     

    Have you tried to disable the new designer? Sometimes the new interface has some issues with the null expression. 

     

    Let me know if it works for you or if you need any additional help!

    Hi @MB29 ,

    I just tried updating the date column to null in Classic Designer,the flow works fine without errors.

    Please switch to classic designer and re-create Update item control,then try again.

    Best Regards,

    thx much, that did the job. 


    The other side effect was that that switching from new to old designer emptied all the fields in my other condition path for the creation process 😂.

     

    but at least it now works as expected. 

     

    cheers 🍹
