Expression of type: 'String' does not match the field: 'folderPath'. Expected type is 'object'.

Hi Rutuja1997,
Based on the error " Double quoted string is not allowed"
Expression of type: 'String' does not match the field: 'folderPath'. Expected type is 'object.

can you try the below path :

{
  "folderPath": @concat('Directory_name/', activity('Filter1').output.Value[0].name)
}

Hi Fabric Community,

Apologies for late feedback.The issue was solved by using set variable activity.I stored the concatenated string in set variable and passed that in the folder path.That way i could solve that problem.
