Trying to pass optional values from powerpass to a flow

For context, I am builing a PowerApps app with Cosmos NoSQL as the DB. In order to connect to it and do queries, I am creating flows. Right now, my flow consist of a PowerApps V2 step to gather the input parameters, and a Create/Update Document V3 to send the data to my CosmosDB. The issue I have right now is that I a trying to pass an optional date input to the Flow. However, if I pass a Blank() it gives me an error that the flow is expecting a String and not a null, and if I pass a "", it tells me that it is expecting a date value. On the PowerApps V2 step I have an optional date input, and on the PowerApps function I am passing the variable as {date_3: Blank()}. Any idea how to pass the optional parameter?

For optional parameters that you don't want to pass a value for you should pass a record containing a null value. Instead of {date_3: Blank()} it should be {date_3: null}

@Pstork1 thank you for the answer. I have tried to pass null, but it does not get recognized in my PowerApps editor and throws an error.
