Hey there,

I´m experiencing a really Strange behavior with the change node.

If you check out my simple example Flow you will see, that the first change node does exactly what it should and outputs data, while the second doesn´t. I really can´t figure out why that happens? Maybe i´m missing something?

Kind regards

What I would do is make a copy of the change node that is not working and then remove half the replaces and see it]f it works. If it does the add in some more of the replaces (or use a copy of the copy so you don’t have to type things in) and test again. This way you should be able to isolate the replace that is causing the issue.

Yup, it's [ in the substitution for 36.

That´s Scary :smiling_face: Thanks for pointing that out. Didn´t think this could mess up the whole node.
