My app works well on the local host but it doesn't work when deploying on shinyapps.io. No anysetwd()is used in the code of app.
This is the error I get when running the deployed app URL:
An error has occurred
The application failed to start.
exit status 1
These are the packages used in app:
library(shiny)
library(bs4Dash)
library(shinydashboard)
library(fresh)
library(psych)
library(DT)
library(vroom)
library(ggrepel)
library(ggExtra)
library(colourpicker)
library(shinyWidgets)
library(shinyjs)
library(slickR)
library(png)
library(ggplot2)
library(dplyr)
library(tidyr)
I think the problem is that Gene-expression-data-GDSC.csv, which is a very important input file, doesn't upload to the /srv/connect/apps/cGEDs-dev as it is stated in the logs. Can the problem be because of large size of the file (167 MB)? How can I fix that? These are the logs:

EDIT
@gokhancan told me the app might not be able to find the csv file so I got the working directory of server using print(getwd()) according to his recommendation and then used print(list.files(getwd(), recursive = T, full.names = T))to print names of files inside that directory. Noticing logs, the working directory is /srv/connect/apps/cGEDs-dev and the Gene-expression-data-GDSC.csv is present in the www directory of the server directory, but it gives an error: 'www/Gene-expression-data-GDSC.csv ' does not exist in current working directory ('/srv/connect/apps/cGEDs-dev').
What is the problem? These are the logs I get:
# some log outputs

Okey after these tons of comments I've created a simple shiny app.
Here is my app directory:
└───sapp
│ server.R
│ ui.R
│
└───data
testdata.csv
server.R
library(shiny)
# Define server logic required to draw a histogram
shinyServer(function(input, output) {
print(getwd())
print(list.files(getwd()))
t = read.csv('data/testdata.csv')
# some code blocks........
#......................
})
ui.R
library(shiny)
shinyUI(fluidPage(
# some code blocks........
#......................
))
And I deployed my app to shinyapps.io.
Now first, you can find the output of print(getwd()) or a similar output from the "Logs" tab of the application deployed on shinyapps.io.
My testdata.csv file located inside "data" folder. So you can see the output describing this folder later in this sentence.
Here is the log output from shinyapps.io:
# some log outputs............

As you see, output of print() function is here. I think this answer might help you.
