Because property 'blah blah' does not exist

(0) ShareShare
ReportReport
Posted on by 40

I've read similar articles that have fixed similar solutions but none of those worked for this one, so forgive me if this is duplicative.

 

Here we go! 🙂

 

I have a manually triggered flow. 

1st action 'list rows present in a table' ... this is an excel file

2nd action, which is a loop, 'Apply to each' with the value parameter from the first action/the excel

 - 1st action in this loop is 'Get items' from a sharepoint list

 - 2nd item in this loop is another loop 'Apply to each'

    - The value parameter here is from the sharepoint list

    - 1st action in this nested loop is a simple 'Condition' to compare a field from the excel and the sharepoint list.

       - If Yes, 'Create item' in a sharepoint list........ this is where the problem is.

       - If No, do nothing. 

 

In the 'Create item' action above I am using an expression to call a date, or item, from the excel, the very first action, so that I can manipulate it and use it as a date that Sharepoint will accept.  Here it is

 

converttoutc(addDays('1899/12/30', int(item()['Completion Date']), 'yyyy-MM-dd'), 'Pacific Standard Time')

 

The Completion Date property is from the excel... the error code tells me that the property is not available and that the available options are those from the Sharepoint list.
 
So, I just need to figure out how to call the Completion Date property in this expression so that it works.
 
Btw, all other properties from the excel are available as Dynamic items but as you may know, we need to use an expression to translate the date to a format that MS List will accept.
 
Thanks in advance!

    Try to update your expression to this: item()?['Completion Date']

    That error pops up when Power Automate gets a null value. The question mark works like this:"If there is a value do the actions, otherwise don't do anything"

    Thanks msabau!

     

    However, after adding the ? as you suggested I got this.

     

    Unable to process template language expressions in action 'Create_item' inputs at line '0' and column '0': 'The template language function 'int' was invoked with a parameter that is not valid. The value cannot be converted to the target type.'.

     

    Interestingly enough, the flow worked just fine when I removed the filter and just added a dynamic value from somewhere else int the able I'm pulling from...

     

    AND

     

    When I ran just the item part as an express it returned null in the MS List but did the Dynamic value just fine.

     

    AND

     

    When I run the entire expression both with and without the ?, outside if this nested loop, it works just fine.

     

    I'm stumped again 🙂

    Found the answer!!!!!!!

     

    To reference a property outside of a nested loop you must use items('<action name>')?['<item name that you want>']

     

    So my final expression looked like this 

     

    converttoutc(addDays('1899/12/30', int(items('Apply_to_each')?['Completion Date']), 'yyyy-MM-dd'), 'Pacific Standard Time')
