When my date is empty, its passed as an empty string and not as blank which gives an error

Hi, 

I am currently  working on a flow that updates data in CRM. (via Common Data Service)  One of the fields contains a date. This date can be empty or have a value. When the date has a value, it is parsed using formatDate().

 

As my date is stored in a variable, I'll also pass this variable on to CRM.

However, if my date is null, it will now automatically pass on an empty string as the date. This gives me the following error: "DateTime is less than minum value supported by CrmDateTime. Actual value: 01/01/0001 00:00:00, Minimum value supported: 01/01/1753 00:00:00"," because it transmits empty variable as an empty string.

Is it possible to make sure that I don't pass on an empty string but nothing at all? 

A solution can be to work with a set of conditions but this seems a bit cumbersome when you have several dates that can be empty.

Hi @Esli 

 

In that case what you could do is generate the JSON Schema with all the elements. Pass your JSON results to schema step to validate it. Later in your step evaluate from the JSON flow step. Hope it make sense. If note send me the full JSON schema. I will try to put something together.

Hi @Esli 

 

Try using the expression function below

 

@not(empty(triggerBody()?['yourdatecolumname']))

 

Thanks

My response message will still have an empty string

{

     "OrderNo": "AB123",
     "StartDate": ""

}

 

I just wish it parsed without the date field. What the normal behavior is when a field is left blank.

 

{

     "OrderNo": "AB123"

}
