Process Problem

fokko

Hello dear,

I have a question to my process. It seems that it works, but at the operator "join, left side" I get an exclamation mark. What is the problem, how can I fix it?
Thanks

If you open the "Problems View" you can see an overview over all problems.

There you see

The attribute 'metadata_path' is missing in the input example set.

for your join operator.
