I can no longer upload files

Hi Greg,

No, it doesn't come from the headers, sorry.

I can get this Curl query to work correctly:

curl -X POST https://content.dropboxapi.com/2/files/upload \
    --header "Authorization: Bearer sl.B_2..." \
    --header "Dropbox-API-Arg: {\"autorename\":false,\"mode\":\"overwrite\",\"mute\":false,\"path\":\"/Test Dropbox.odt\",\"strict_conflict\":false}" \
    --header "User-Agent: python-requests/2.25.1" \
    --header "Accept-Encoding: gzip, deflate" \
    --header "Accept: */*" \
    --header "Connection: keep-alive" \
    --header "Content-Type: application/octet-stream" \
    --write-out "%{http_code}\n" \
    --data-binary "@/home/prrvchr/Test Dropbox.odt"

On the other hand, if I use Python/Requests instead of Curl, it gives me a 404:

import requests

url = 'https://content.dropboxapi.com/2/files/upload'
headers = {'Content-Type': 'application/octet-stream',
           'Dropbox-API-Arg': '{"autorename": false, "mode": "overwrite", "mute": false, "path": "/Test Dropbox.odt", "strict_conflict": false}',
           'Authorization': 'Bearer sl.B_2...'}
data = open('/home/prrvchr/Test Dropbox.odt', 'rb')
response = requests.put(url, headers=headers, data=data)
print("Status Code: %s" % response.status_code)
response.close()
data.close()

I don't see why...
