Publishing dataframe, get Internal API Error when making POST request

I am using pyrasgo version 1.6.2

I am submitting code like:

d1 = rasgo.publish.df(df=scores, name="MWNAME", description="sample result", verbose=True)

I am getting an error that says:

API Error: Internal API Error when making POST request

Please check the Rasgo GUI to see if the dataset eventually published. This error is typical when the dataframe is large and it timesout in the API, but it might have actually succeeded.
