Convert time zone failed

Posted on by Community Power Pla...

Hi Experts,

I am new to the world of Power Automate/Flows and have been trying to edit an existing flow which looks to run fine until the 'Convert time zone' stage where I get the following error:

InvalidTemplate. Unable to process template language expressions for action 'Convert_time_zone_3' at line '1' and column '25969': 'In function 'converttimezone', the value provided for date time string '' was not valid. The datetime string must match ISO 8601 format.'.

This is what I have within convert time

Base Time: StartDate

Format String: Full date/time pattern (short time) - Monday, June 15, 2009 1:45 PM [f]

Source time zone: (UTC) Coordinated Universal Time

Destination time zone: (UTC+00:00) Dublin, Edinburgh, Lisbon, London

Does anyone have an idea why this error is occuring?

Thanks

Ramson

@ramaseko

Thanks for your response Kyle ‌‌

Unfortunately it doesn't let me save an image on here.

The below is what I have in start date:
@{items('Apply_to_each')?['StartDate']}

Apply to each - is for each language variation where I am wanting to convert to local time - hope that makes sense?

Thanks

@ramaseko

Can you go to the output of one of the failed runs and copy/paste the input value of "Start Date"?
It seems that the flow doesn't like the format of the date/time that you are passing in, and I am trying to determine what format that is currently.

Also, I'm not really understanding what the referenced "Apply to Each" loop is iterating through, can you be a little more specific? is it a table in a spreadsheet? A SharePoint list?

thanks,
Kyle
