Datasetnotfoundexception even though the dataset exists when using sempy fabric functions

Hi,

I am currently getting DatasetNotFoundException: Dataset '<datasetId>' not found in workspace '<workspaceId>' 

(Just replaced the actual values with <>)

The issue is the dataset actually exists. I can even see the dataset when querying via the API. 

import sempy.fabric as fabric
import json

workspaceId = 'workspaceid_here'
client = fabric.FabricRestClient()

try:
    response = client.get(
        f'https://api.fabric.microsoft.com/v1/workspaces/{workspaceId}/semanticModels'
    )
    print(response.text)
except Exception as e:
    print(e)

When I try using the list_columns() function, I get the datasetnotfoundexception error as stated above. (again, actual values were replaced in this post)

import sempy.fabric as fabric

df_columns = fabric.list_columns(dataset=datasetid, workspace=workspaceId)
df_columns = df_columns[['Table Name', 'Column Name', 'Data Type']]

display(df_columns)

Even using list_datasets() returns an IndexError: list index out of range

import sempy.fabric as fabric
text = fabric.list_datasets() 
display(text)

Any ideas why this is happening? Why the fabric package functions cannot find the datasets even though they actually exist? 

Thank you.
