Can't make DatePicker output as Date instead of String

Posted on by JonaV

I'm building a Power App which outputs the date from DatePicker to Power Automate, where a meeting is added to a calendar, with as date the output from DatePicker.

But I can't get it to work. The trigger I use is PowerApps V2. When I use the "Date" option, the flow doesn't receive it because it's a string, not a date.

When I use type "Text" in the flow trigger, it works and the flow receives the date I selected in de PowerApp, but the "add to outlook calendar" function doesn't work because it's a string.

I've been trying to fix this for a week now, I watched lots of videos, many topics, tried so many things but nothing works...

One of the things I tried was converting the string to a date (tried different formulas) but none of them worked, because it's a string...

Even if I change the format in the DatePicker properties, it's always "dd-MM-yyyy", and a string.

I think the problem and fix are in the PowerApp, but I can't get it to work. So I hope someone can help me fix this.

If you need more information, let me know!

Just put a test together for you.

Here is what i did

my flow is from powerapps and has a trigger date variable / date

compose is as follows

formatDateTime(triggerBody()['date'])

Start & End time in calendar creation are both just the output of the compose step. In my example theres no time, so sets it by default to 12am, but you can edit this into it as well

my button in powerapps functions as follows

datetest.Run(Text("2022-10-26"))

yyyy-mm-dd is correct format for flow to see it as a date on the pass through, and the compose step will convert it to a date

and pressing button created the item in my calendar as seen below

Thank you for your help!

So, I added the compose step and now my flow is the same as yours.
In powerapps, I used the following code:
'PowerApps-GeenHelpdesk'.Run(Reden; 'Office365-gebruikers'.MyProfileV2().displayName; Text("2022-10-26"))
Note: the first two (Reden & Office365-gebruikers'.MyProfileV2().displayName) are used for other information (and are working).
It goes into the flow like I entered (2022-10-26), but still as a string. The compose action can convert it to ISO, and Add To Calendar works too, thank you!

But when I change Text("2022-10-26") to Text(dateDatum; "yyyy-mm-dd") I get an error because it's a string, before it even goes to the flow. (PowerApps-GeenHelpdesk.Run failed: {"error": {"code": "TriggerInputSchemaMismatch",
"message": "The input body for trigger 'manual' of type 'Request' did not match its schema definition. Error details: 'String '18-10-2022' does not validate against format 'date'.'."}}

Do you know a solution for this?

Your date is coming off a date picker right? have you tried this? Seems to work on my end

Text(DatePicker2.SelectedDate,"yyyy-mm-dd")
