Do you have any advice?
I already deploy a lighter version of the app which is working well,i only add up a csv file of 2MB and now it is not working.

Executing your app takes more memory than it is available to it on shinyapps.io, if you have a paid account you can try increasing the memory limit, if not, try to reduce the memory requirements or consider another hosting option.

Thanks a lot that explains it.
