Title says it all,
Basically I have a workflow:
Adding a prefix to the new attribute results in the new attribute not to have any values.
Running with prefix:
Running without prefix:
Also if I add a prefix, for example _, and have a new field I wish to extract, i.e. “ID” which should result in a new column “_ID” with values, it instead replaces the original id field with the new values, totally ignoring the requested “_” prefix.
Workaround is to rename the original values with a prefix before extracting second set of values from nested json.
