Weird concat behaviour

(0) ShareShare
ReportReport
Posted on by 281

Hi there,

I have a concat action that behaves really weird. Want to combine strings from an array.
But the concat doesn't seem to recognize the array as an array, but seems to treat it as text.

So I've added an action that counts the number of items in the (supposed) array to check if the input really is an array. And it is.

So what I'd expected is to get a string like so: "test.ITA_prod_AddressDetails.csv"
Does anyone have an idea how to solve this?

    Hi @Imke ,

     

    I guess iteration through all array elements is a solution. Something like:

    You will have to cut the last char of the resulting string.

     

    Hope it helps !
