API 'Connection Aborted' Error
Hello!
I'm downloading files from an App Folder. I am downloading each one by one, totaling over 3000 files. I left the program to run and after 201 requests I got the error pasted below. I don't have a VPN or anything that would change my wifi connection as far as I know. Here is the code I am using:
print("Initializing Dropbox API...")
dbx = dropbox.Dropbox(AUTHORIZATION_TOKEN)
topn = filenames[:len(filenames)]for val in topn:
filepath = val
#download a file to the local machinewith open("/Users/<PATH>/dataimport.csv.gz", "wb") as f:
metadata, res = dbx.files_download(path=filepath)
f.write(res.content)
print("download complete")
The error:

Does this reliably reproduce for you?I just tried this code out, filling in the missing pieces, and the issue didn't occur for me. If it's not consistent, it could be due to random transient server availability or networking issues, in which case you may want to implement additional retries (ideally with exponential backoff) to handle transient issues like this.
If it is consistent though, does it always reproduce after 201 requests, or perhaps on the same file? If it reproduces on the same file, how large is the file and how long does it take on that file before failing?
