Hi everyone I am trying to make a string match (addresses) of two datasets using the String Matcher node, but the real dataset are quite big so I need to split in groups the data by a variable called “Country”, so I can match the addresses of country A of dataset 1 versus the addresses of country A of dataset 2. I was trying to make this workflow, but I came with the following error “Can’t merge FlowVariable Stacks (likely a loop problem)”
I came with a solution using another node using the String Similarity node
Despite of the above solution I want to check my results with the String Matcher, so I beg if anyone can help me with that solution.
