@UserTrue Thank you for your advice. Yes, at first I tried the built in mongodb with it's module. It made me quite fast switch over to MySQL and the appropriate node.js module ;)
I don't know if i'm doing something wrong but if i put inside the "Read file" command an resource file path "lines from file" the function doesn't work
Doing so means that there is path to another file inside your original file.
Just use resource anywhere in your code.
