Trying to export files from folders and subfolders to Nakala
Hello.
I'm part of a project and i need to export all the Dropbox's files to Nakala which is a data warehouse.
I'm having difficulties listing the Dropbox folders, i think the script doesnt recognize them even when i have the right path to them
Here is the code :
Spoiler
import dropbox
import requests
# Dropbox and Nakala authentication
DROPBOX_ACCESS_TOKEN = ''
NAKALA_API_URL = "https://apitest.nakala.fr/data/"
NAKALA_API_KEY = "01234567-89ab-cdef-0123-456789abcdef"
dbx = dropbox.Dropbox(DROPBOX_ACCESS_TOKEN)
# Step 1: Recursively list folders and files in Dropbox
def list_all_folders_and_upload_to_nakala(folder_path=""):
try:
result = dbx.files_list_folder(folder_path, recursive=True)
print("Folders and files in Dropbox:")
for entry in result.entries:
if isinstance(entry, dropbox.files.FileMetadata):
file_path_in_dropbox = entry.path_lower
print(f"Processing file: {file_path_in_dropbox}")
# Download the file from Dropbox
file_content = download_from_dropbox(file_path_in_dropbox)
# Upload to Nakala
if file_content:
print(f"Uploading {entry.name} to Nakala...")
upload_to_nakala(entry.name, file_content)
elif isinstance(entry, dropbox.files.FolderMetadata):
print(f"Folder: {entry.path_display}")
except Exception as e:
print(f"Error listing Dropbox folders: {e}")
# Step 2: Download file from Dropbox
def download_from_dropbox(file_path):
try:
metadata, res = dbx.files_download(path=file_path)
print(f"Downloaded: {file_path}")
return res.content
except Exception as e:
print(f"Error downloading from Dropbox: {e}")
return None
# Step 3: Upload file to Nakala
def upload_to_nakala(file_name, file_content):
files = {
'file': (file_name, file_content),
}
headers = {
'Authorization': f'Bearer {NAKALA_API_KEY}',
}
try:
response = requests.post(NAKALA_API_URL, headers=headers, files=files)
if response.status_code == 200:
print(f"File {file_name} uploaded successfully to Nakala!")
else:
print(f"Error uploading {file_name} to Nakala: {response.status_code}, {response.text}")
except Exception as e:
print(f"Error during Nakala upload: {e}")
# Main workflow
folder_path_in_dropbox = "/Sète"
list_all_folders_and_upload_to_nakala(folder_path_in_dropbox)
I would like to know why this doesnt work, when i have the folder created
Thanks you.
A "path/not_found" Dropbox API error indicates that the API call failed because there was nothing currently found at the specified
pathin the connected account under the relevant root. For example, this can happen if there's a mistake or typo in thepathvalue the app supplies, if the file/folder has been renamed, moved, or deleted from that path, if the app is not connected to the correct account for that particular path, etc.When specifying the path, make sure you provide the full and accurate path for the desired file under the relevant root. For example, if you have a file named "example.csv" inside a folder named "folder", the path would be
"/folder/example.csv". You can find more information on path formats here.I see Здравко already helpfully covered some of this, but to elaborate a bit, here are several things you can check in particular to debug this:
- Make sure you're using a currently accurate
pathvalue: You can use files_list_folder and files_list_folder_continue to list the contents of a folder so you can check what the correctpathvalues would be for items in those folder(s). To list the root, setpathto the empty string""when calling files_list_folder. You can use thepath_loweroridvalues returned for the files/folders in that folder to interact with those files/folders.
- Make sure you're connected to the correct account for the
pathvalue you're using: You can use users_get_current_account to check which account the app is connected to.
- Make sure you're using app folder-relative paths, if your app is registered for the "app folder" access type: Apps with the "app folder" access type can only access the contents of the special app folder that gets automatically created for it. If your app has the "app folder" access type, then it will only be able to access files in the app folder, and the root for any path value supplied by that app will automatically be the app folder root. You can find more information on app permissions here. For example, If your app has the app folder access type and you're trying to access something you can see on the Dropbox web site at
"/Apps/<app folder name>/folder/example.csv", you should only send thepathvalue as"/folder/example.csv". Alternatively, if your app is registered for the "app folder" access type but you need to access contents outside the app folder, you'll need to use a different app registration with the full Dropbox access type instead (or you can move the contents into the app folder).
- Make sure you're accessing the relevant root: When using an app with the "full Dropbox" access type, API calls default to the member folder, but if you're trying to access the "team space" (only applicable to members of a team with the "team space" configuration), you'll need to configure that as the root explicitly, as covered in the Team Files Guide.
Given the existence of "Applications" in your screenshot though, it seems like you may have registered an app with the app folder access type, but are trying to access a folder "/Sète" outside the app folder, which would fail, so take note of the third list item above in particular.
- Make sure you're using a currently accurate

Hi Cryo,
Is there something in your folder you're trying to process? 🤔 What does actually your script output? (eventual error message or something like)
Something else that may confuse you is skipping the fact that folder listing is in pages (or may be at least). Using files_list_folder returns only the first page, not entire folder content! You didn't check has_more field to see if there may be next pages. Do this and call files_list_folder_continue too whenever needed for full folder content list. 😉
Hope this gives direction.
Yes there is pictures files.

As the error message shows, you don't point your folder in correct way. There are number of possibilities, but instead of I speculate, better just you start from the root - empty path instead of some concrete - it's always correct one.
Let's see what will get up.

Thanks you very much !
I didn't have the folder in the application folder, i just put it here and it is working.
Have a great day !
