Issue: Random 400 Client Error when pushing dataset
State: closed
Author: msis

## Describe the bug
When pushing a dataset, the client errors randomly with `Bad Request for url:...`.
At the next call, a new parquet file is created for each shard.
The client may fail at any random shard.

## Steps to reproduce the bug
```python
dataset.push_to_hub("ORG/DATASET", private=True, branch="main")
```

## Expected results
Push all the dataset to the Hub with no duplicates. 
If it fails, it should retry or fail, but continue from the last failed shard.

## Actual results
```

Comments:
did you ever fix this? I'm experiencing the same

I am having the same issue. Even the simple example from the documentation gives me the 400 Error


> from datasets import load_dataset
> 
> dataset = load_dataset("stevhliu/demo")
> dataset.push_to_hub("processed_demo")


`requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://huggingface.co/api/datasets/REDACTED/commit/main (Request ID: e-tPnYTiCdB5KPmSL86dQ)`

I "fixed" it by initializing a new virtual environment with only datasets==2.5.2 installed.

The workaround consists of saving to disk then loading from disk and pushing to hub but from the new clean virtual environment.
