Hello everyone,  
I am currently working on a flow and I have now encountered the problem that the "exec" function gives me a string that I cannot process in the switch.

I would like to use the function == in the switch. My problem now is that the string I get from the previous function has a manual line break, which I can't copy into the switch.

I have tried everything possible, but I am just too inexperienced with Node Red and don't know how to make it work.

My approaches:

- Use Slice in a Function (I couldn't get any output)
- Switch option "contains" (no difference)

Output exec:

You can use a function node to trim the payload before the switch

```auto
msg.payload = msg.payload.trim();
return msg;

```

or use JSONata in the switch property

```auto
$trim($$.payload)

```
