AssertionError: Expected content-type to be application/json, got 'application/grpc'
Hi, everybody! I have a simple Python script to create an archive and store it in Dropbox.
import subprocess
import os
import dropbox
import shutil
from datetime import datetime
class...
I just renewed the token, and all is good. Thank you for your time Greg-DB

Dropbox StaffThanks for the report! This error indicates that the Dropbox API servers did not respond with the expected format.
I just tried this out myself though, and I wasn't able to reproduce this. This kind of issue could just be a result of temporary server issues. Are you still seeing this problem?
If you are still seeing this, please let me know:
- about what percent of your calls fail like this
- if this code was previously working for you, and if so, when you saw this problem start occurring
- whether or not other calls, such as `self.dbx.users_get_current_account()` also fail like this for you
Sorry for the late reply.
- about what percent of your calls fail like this
All of them
- if this code was previously working for you, and if so, when you saw this problem start occurring
No, this is a new script for me, I wrote it with the help of this post
https://www.dropboxforum.com/t5/Dropbox-API-Support-Feedback/python-upload-big-file-example/td-p/166626
It worked for others without problems. - whether or not other calls, such as `self.dbx.users_get_current_account()` also fail like this for you
Unfortunately yes. The token was provided to me by my colleague. Could it be restrictions of trial account perhaps?
print(dbx.users_get_current_account()) AssertionError: Expected content-type to be application/json, got 'application/grpc'
Thank you for your assistance

Thanks for following up. The API functionality you're attempting to use is available to all Dropbox plans/trials, and even if an API error is returned, it shouldn't be sent with that Content-Type.
It's unclear what would be causing this, so we'll need to look into this further. Can you please try running the following at least 5 times and send me the output? This will enable more verbose output which may be helpful for investigating this issue:
import http.client http.client.HTTPConnection.debuglevel = 1 import dropbox dbx = dropbox.Dropbox('ACCESS_TOKEN_HERE') print(dbx.users_get_current_account())Be sure to replace ACCESS_TOKEN_HERE with the access token you're using. As long as that access token starts with "sl." and it has been more than four hours since the access token has been created, please leave it in the output as it would be expired anyway and may be helpful for investigating this.

Exception has occurred: AssertionError Expected content-type to be application/json, got 'application/grpc' File "/home/bazhin/dropbox/test2.py", line 6, in <module> print(dbx.users_get_current_account()) AssertionError: Expected content-type to be application/json, got 'application/grpc'Well, I decided to create my own app for testing on my own current account.
Permission type - account_info.read - Scoped AppAnd
print(dbx.users_get_current_account())works just fine now.
Then I added files.content.write permission and tried my script from the first post and gotException has occurred: AuthError AuthError('1c1aa051ebc4408297c28154348ecaf8', AuthError('missing_scope', TokenScopeError(required_scope='files.content.write'))) File "/home/bazhin/dropbox/dropbox_backup.py", line 15, in upload upload_session_start_result = self.dbx.files_upload_session_start(f.read(self.CHUNK_SIZE)) File "/home/bazhin/dropbox/dropbox_backup.py", line 54, in <module> uploader.upload(archive_name, archive_size) dropbox.exceptions.AuthError: AuthError('1c1aa051ebc4408297c28154348ecaf8', AuthError('missing_scope', TokenScopeError(required_scope='files.content.write')))But I guess I have to wait for permission update or something, haven't I?
