Hey, so i have a flow where i have email in an excel with multiple rows which are duplicates.

 

I used select to gather the email and then apply to each to unionise the emails so they singular to progress.

 

I made a slight amend today and now it is saying union needs an array and not a string?

    Check for additional whitespace in the Apply to each input field.

    In your screenshot it looks like there is a space to the left of the expression box 😉

    For anyone who is viewing this and has the same issue.

     

    I had to rebuild the whole flow from apply to each to the end. Same union in the new apply to each but it still didn't like it. Must have gotten corrupt somehow.
