Assign: Object reference not set to an instance of an object. Error

whenever I am trying to store value in array variable from dictionary its showing error like “Assign: Object reference not set to an instance of an object.”

plz help

Have you initialized the value of RowData?

No, I didnt

and the array size is dynamic

Hi

Kindly check once with a writeline activity with the sand input used in the Assign activity do that we could see the result if there in output panel or we need to check the input before assigning
And also
Usually array size can’t be dynamic
Kindly use list variable in that case to store the collections
