Multiple Approver Fields Error When A Field is Blank

(0) ShareShare
ReportReport
Posted on by 72

Hello. I have the below flow to where I have 3 fields on my list of possible approvers. The item will not always need all 3 approvals so any of the 3 fields may be blank. My flow is sending the approvals out to the people that are listed in any of the 3 fields but I am receiving the following error in the screenshot. Anyone know how to fix this? Note that this trigger is when an item is created on the list. The error is stating that the Assigned to field is missing but it's not and you can see that it kicked off fine for the CO approval but failed for the other 2 because they did not have a name in them. Thanks in advance.

    Ok, this might work and I will feel silly if it does. Let me give it a shot. Thanks!

    We can probably clean the flow up a bit, instead of running 3 approvals, do just 1 and pick to either wait for all the approvals or just 1 of them. That way you dont have to do the same steps 3 times. 

     

    Then just put the approver field to whats written below but switch to your columns, this way your send approval wont fail if one of them is empty. 

    Approver1;Approver2;Approver3

    It's a people picker field and it emails just fine when there is a name in any of the 3 fields but it errors out if any of the 3 fields do  not have a name in it.

    The Assigned field needs to be an email, is the dynamic data you have there an email?
