Search this channel, multiple people have had the issue, it's discussed in those threads 🙂

@shadman Ashrafi use the if validation on string before doing split

It's a new version of the notorious "unexpected error"

There is no split funtion in the entire code.

@shadman Ashrafi as I said search for it in this channel and you will find answers 🙂
