Posted on by Community Power Pla... Microsoft Employee

Hi All,

I've built a Flow to my PowerApp which updates a document library.

I have added a DOB field in the powerApp. I have then created a Variable in my Flow (see below)

The variable runs successfully however when i add the variable in the update file properties i receive an error (see below)

See below for update file properties details

Can anyone advise on what I may be doing wrong here or why the Flow is failing please.

Thanks in advance.

Check to see the value in the variable when the flow runs.

It looks like the format is not of type datetime.

Hey,
In the value it's showing a date just the same as I input into my PowerApp

Could there possibly be an issue with my Column in the Library

You date 13/12/1995

13 cannot be a number for month

thats why it is failing

After my last reply I went into site settings and changed the regional settings and set time zone to Dublin, Edinburgh... and Region Locale to English (United Kingdom) ran the App again and it still fails. I would have thought this would default the date to dd/mm/yyyy.

P.s The flow runs if the number is under 13 making me think it's sticking to the American date format somewhere, even though it displays as uk date when i select this from the Powerapp

Hi @Anonymous ,

You could use the following expression to change the date format to the expected one.

concat(split(variables('varDOB'),'/')[1],'/',split(variables('varDOB'),'/')[0],'/',split(variables('varDOB'),'/')[2])

Then you could fill the output of Compose in the date field.

Best Regards,

Reza,
I can't resolve this date issue even though all looks fine in the SP site. Your solution does work bit unfortunately due to my site settings it doesnt.
Thank you very much for helping out. 👍

Hi @Anonymous

Although the solution has worked, it is not ideal.

You will need to analyze why the dates are not coming through in your regional locale.

You would not want to plug in an expression every time you build a flow dealing with dates.

Regards,

Reza
