@kevindGG I don't think the Filter Array action is necessary in your flow case. You need to use the Filter Query in the Get Items action.
I'm using the Classic Designer — I find the New Designer a bit buggy.
In my SP list I have 3 items with today's date.

The filter query in my Get Items action would look like this. You will need to use the internal column name of your Date column. Keep in mind that the internal column name may not always match the name displayed in your Sharepoint list. If you aren't sure how to get the Internal Column name, you can refer to this section of one of my YT Tutorials. Ensure that the dynamic content for current date/time is between single quotes.

Return Count of Items
Whenever I use a Filter Query in a Get Items action, I always like to return the count of items returned in a Compose action. This is helpful when building a flow and can also be used to troubleshoot your flow.
Insert a Compose action. Add an Expression. Use the length() function.

Select the Dynamic content tab and insert the value dynamic content from the Get Items action into the length() function.


Run a test. Review the outputs. Ensure the number is what you are expecting. If not, there are a couple of things you can do.

Check the filter query. Toggle open the Get Items action and check the date output. Depending on what time you run this flow and your timezone—the output of the utcNow() function may output the next day.

If your SP list has a lot of items, you may need to toggle on pagination and set a threshold. Click on the three dots and select settings.

Toggle on pagination and set a threshold. Don't forget to scroll to the bottom and press Done.

Condition Check
Add a Condition action to your flow. If items have returned (aka there is number stored in the Compose action—that is not equal to 0), add the rest of your actions to the Yes branch. If not, do nothing.

Place all other actions into the YES branch. Ensure you are selecting the value dynamic content from the Get Items action to loop through.
