Hi @DJanyavula Thanks for reaching out to us!

Can you provide a little more information about the problem so we can investigate it further?

• What version of Python are you using? (Looking at stacktrack, I'm guessing it's 3.7)
• Which version of the SDK are you using?
• How can we reproduce this problem? Maybe you could also provide some sample code?
• Could you define what you mean by "many" requests? How many?
• How often does this happen (occasionally or always)?

Thanks

Hi @mwwoda ,

I will try to answer your questions, on behalf of my colleague @DJanyavula .

Packages versions used: Python 3.7 boxsdk 2.14.0

We were using this Box api calls for 11 files to be uploaded over a time span of 15 mins. It is not that many requests and we have not exceeded the api calls per second. If we have exceeded the limit, we yse to get the http error log of "exceeded api limit".

We have been using this function since few months now and for past 2 weeks, it is giving this time-out error always. When we use it for 2-3 file uploads to box, it works without issues.

You can replicate the scenario with below code. Just replace the box api token and the excel file folder names with actual path and file names.

```Sample code snippet below ````

"""This python module uploads the local files to given box folder""" import json import os from boxsdk import Client, JWTAuth

class BoxReader: """A reader class to connect to Box, read and write files from and to Box with local sources/targets or s3 sources/targets"""

def __init__(self, box_api_token: str = "/path/to/box_api_key.json"):
    """
    An interface for connecting to Box. The credentials will be stored and fetched from Cerberus
    """
    box_key = json.loads(box_api_token)
    private_key_path = "/tmp/private_key.pem"
    with open(private_key_path, "w") as private_key_file:
        private_key_file.write(box_key["boxAppSettings"]["appAuth"]["privateKey"])
        private_key_file.close()

    # Use the JWT credentials to create a box application client
    auth = JWTAuth(
        client_id=box_key["boxAppSettings"]["clientID"],
        client_secret=box_key["boxAppSettings"]["clientSecret"],
        enterprise_id=box_key["enterpriseID"],
        jwt_key_id=box_key["boxAppSettings"]["appAuth"]["publicKeyID"],
        rsa_private_key_file_sys_path=private_key_path,
        rsa_private_key_passphrase=str.encode(
            box_key["boxAppSettings"]["appAuth"]["passphrase"]
        ),
    )
    self.box_client = Client(auth)


def get_list_files(self, folder_id: int):
    """Get list of all files of a certain folder_id

    Args:
        folder_id (int): Folder ID for box for which files needs to be listed.
    """
    items = self.box_client.folder(folder_id=folder_id).get_items()
    list_files = [(item.id, item.name) for item in items if item.type == "file"]
    return list_files


def upload_file_to_box(self, temp_file, folder_id, file_name: str) -> str:
    """Uploads local file to specified box folder with specific file name

    Args:
        temp_file (NamedTemporaryFile): Local temp file with full path
        folder_id (int): Folder id in box to store the file
        file_name (str): specific file name

    Returns:
        str: name of the file path
    """
    input_file_path = os.path.join(os.path.dirname(temp_file.name), file_name)
    os.rename(temp_file.name, input_file_path)

    files_dict = dict(self.get_list_files(folder_id=folder_id))
    files_dict = {value: key for key, value in files_dict.items()}

    if file_name in files_dict.keys():
        self.box_client.file(files_dict[file_name]).delete()
    self.box_client.folder(folder_id).upload(input_file_path)
    return input_file_path

if name == "main": uploaded_files_path = BoxReader().upload_file_to_box( box_api_token="/path/to/box_api_key.json", temp_file="/local/path/to/temp_output_xxx.xlsx", folder_id=1111111, file_name="output_xxx.xlsx", ) print(f"uploaded_files_path: {uploaded_files_path}")

Hi @mwwoda ,

Is there any update on this ? Just fyi, we have upgraded the boxsdk version to 3.3.0 and now instead of timeout error, the api call gets hanging without finishing. It even kept running for 2 days and I had to cancel the execution.

Code: The box api call is made to the "client.folder.upload()" function in boxsdk package -> https://github.com/box/box-python-sdk/blob/fe00a9eb3434ee14bc4f01332d54c0272ed5f2d3/boxsdk/object/folder.py#L90:~:text=def-,upload,-(

Frequency: The frequency happens, when I am executing a sequential call of box api for PUT request. First 3-4 requests successds without any issue and after that, next call keeps hanging.

Impact: This is even more dangerous than giving a timeout error and this is blocking the application run completely. Could you please check why it's happening and does it happen for other users of yours as well ?

Thanks for considering this bit more urgently.

Hi @arifty, today I used you code to upload 100 files one by one and so far I was not able to replicate this issue you described. I'll continue investigating this tomorrow. @lukaszsocha2

Hi @arifty, today I also wasn't able to replicate this issue on my side, therefore I prepared a simple bash script with uploads all files from a local folder to box folder using curl command. If this script will block the same as using SDK, then we could exclude SDK code as the root of the problem and try to find it either in the network layer or the upload service.

path_to_folder_with_files="/Absolute/path/to/your/local/folder"
developer_token="..."
folder_id="box folder id"

for path in "$path_to_folder_with_files"/*
do
  filename="$(basename -- $path)"
  curl -i -X POST "https://upload.box.com/api/2.0/files/content" \
                               -H "Authorization: Bearer $developer_token" \
                               -H "Content-Type: multipart/form-data" \
                               -F attributes="{\"name\":\"$filename\", \"parent\":{\"id\":\"$folder_id\"}}" \
                               -F file=@"$path"
done

To make it work you should replace values of path_to_folder_with_files, developer_token and folder_id variables. Also can you tell me what it the size of the files you try to upload? Is there any pattern that the execution blocks on small or big files? Waiting for your answer to continue investigation. Best, @lukaszsocha2
