Conditional parameters in designer don't show empty string

Question

I have seen in several situations where in conditional actions the parameters don't show empty strings like "" and if there is a string value like "string" with quotes around it when saving it will remove the double quotes. In the code view it will be there. If someone was in the designer and saw an empty field or a value with no double-quotes when it is supposed to be it could cause misleading decisions.

Hi Christopher Fryett

Thanks for reaching out on Microsoft Q&A!

In the designer view, Logic Apps often hides empty strings ("") and strips quotes for readability. When you save, the underlying JSON in code view still contains the correct representation.

The designer doesn’t show quotes because it assumes you’re entering raw text, not JSON. This can lead to misleading assumptions if someone expects to see "" for empty or quotes for literal strings.

Before publishing, check the JSON to confirm values. Instead of relying on visual cues, explicitly set:

@empty(variables('myVar'))

And consider default values, for example with:

coalesce()

or

if()

Also, you could remove the "" from the Code View and replace it with null.
