hello, did you do bench migrate & bench restart after installing the app and how you are using "gen_qrcode()", in a print format ?

thank you for your reply
yes, i did .

the error saying that you did not supply the text argument to the function, try this and see if it works

<img src="{{ gen_qrcode('test123') }}" width="100" />
