Hi guys,
I have a problem with the if node.
If I perform a data-merge over a function after a “split in batch” and then check the variable “isDev” from the “.env”-function defined before (before the split in batch) for “true” after the batch I get true AND false in one pass. For checkup: Function2 has a console.log($node[".env"].json["isDev"]);
Is this a bug or a feature?
For a better understanding I have built a pseudo-workflow.
The workflow was executed on version 0.95.1
In the real Zenario a http request with different configurations is executed within the “Split in Batch”. The result should and will be summarized afterwards.
