Issue: "Couldn't upload dataset. TypeError: NetworkError when attempting to fetch resource" when trying to upload a csv dataset

[c0pper]

Description:
When attempting to upload a CSV dataset to the langsmith web ui using the provided functionality, the process fails with the error message "Couldn't upload dataset. TypeError: NetworkError when attempting to fetch resource". This error prevents the successful submission of the dataset, hindering progress on data analysis or processing tasks.

Steps Taken:

Ensured that the CSV file is correctly formatted and contains valid data.
Checked the network connectivity to ensure there are no issues with internet access.
Attempted to upload the dataset multiple times, but consistently encountered the same error.
Reviewed relevant documentation or support resources provided by the service, but did not find a solution to the issue.

Expected Outcome:
The dataset should be successfully uploaded to the server without encountering any errors, allowing for further data analysis or processing tasks to proceed.

Additional Information:

Tried in Python following this guide as well https://docs.smith.langchain.com/evaluation/faq/datasets-client#create-dataset-from-csv with the following error trace:

urllib3.exceptions.SSLError: EOF occurred in violation of protocol (_ssl.c:2384)

The above exception was the direct cause of the following exception:
