formatDateTime error

Posted on by Community Power Pla...

I was running into this error:

Unable to process template language expressions in action 'Create_Document_Review_Reminder' inputs at line '1' and column '2264': 'In function 'formatDateTime', the value provided for date time string '24/03/2021 14:46:10' was not valid. The datetime string must match ISO 8601 format.'.

What is supposed to be the format? The column where this gets created is in a DateTime format of dd/MM/yyyy.

This is the expression that I use where Converted _time_to_NZ is the current time converted to NZ timezone.

formatDateTime(body('Converted_time_to_NZ'), 'dd/MM/yyyy')

Any ideas?

Hi
"Converted _time_to_NZ is the current time converted to NZ timezone"
Which expression/action block did you use to convert utcNow() into NZ timezone?
Thanx!

Here is a screenshot of my flow for the Converted_time_to_NZ. Calculated time is from the Calc_Review_Date_in_International time.
This worked for dates that are 09/03/2020 and 11/03/2020. But it didn't for 24/03/2020. It seemed to be okay if it's MM/dd/yyyy.

Hope this helps

I tried that but I got the below error instead. I am thinking what other option to use aside from formatDateTime.

String was not recognized as a valid DateTime.

Hi @Anonymous,

The reason for the issue will happen is caused by the formatDateTime() function recognize the first unit of the Time String is the month, so if it is greater than 12, it will report it is an invalid date.

So, you could convert the date into a format which month is in the head, for example:

Thanks I tried that but I still get the error 'String was not recognized as a valid DateTime.' The formatDateTime expression applies to the Review Due Date column as shown.

I finally managed to get it to work.

So instead of using 'dd/MM/yyyy', I switched it to 'MM/dd/yyyy' so the expression goes like this:

formatDateTime(body('Converted_time_to_NZ'), 'MM/dd/yyyy')

It finally worked. And my Review Due Date column still goes to dd/MM/yyyy format since I am using the New Zealand timezone in the site's settings.
