This is my app https://sunilmeharia.shinyapps.io/newsentiment/.Locally it works fine but after deployed it produces errors. How can I find what is going on? Can you see my logs?If not I can send them to you.

We don't have enough information to help you out, Could you check what your app's logs say?

are there many places in your code where you use gsub ?
can you recognise the point of failure as it relates to your code ?
