Error message when using Dataset.Tabular.register_pandas_dataframe

I am getting an error when trying to upload and register a pandas dataframe using the experimental method from my local machine using the azureml SDK.

```
Dataset.Tabular.register_pandas_dataframe(dataframe=df,
target=ds,
name=name,
description=description,
tags=tags,
show_progress=True)
```
Where `ds` is the workspace default datastore, `df` is a pandas dataframe and tags is a key value pair dict.


This does work through a jupyter notebook, however, when executing the code from a script it fails. I have never seen this before and couldn't find anything online or in the documentation.

AzureML SDK version: 1.27.0
Pandas version: 1.2.0
