Hey guys!  
I am measuring data from the RasPi with an Exec Node. This measurements come as a string with an endline at the end. I used to have a function node wich replaces the \n. I don't know what i have changed but now i get the following debug-message: "TypeError: msg.payload.replaceAll is not a function"  
I want to have it in "float" format, not "string"

ReplaceAll [requires nodejs v15 or greater](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replaceAll#browser_compatibility). What version of node are you running?

Try `msg.payload.trim()` it should remove any white space, including newline.

Ps, parseFloat will ignore the carriage return and will just work (iirc)
