Hi there,
I'm trying to deploy my pyshiny app, which works great locally, but I am getting this error when I attempt to deploy it:
Validating server... [OK]
Validating app mode... [OK]
Making bundle ... [OK]
Deploying bundle ... [ERROR]: Exception trying to connect to https://shinyapps-upload.s3.amazonaws.com/bundles/application... - The write operation timed out
My app folder only contains my app.py file and a pickled dataframe (totaling 608 MB), which is under the 1 GB maximum. Any insight into what's gone wrong is GREATLY appreciated.
Thanks so much
