I am having a problem with Dask in CODEBK. Specifically, if I call get_news_story() from the Eikon API in a Dask worker I get the following error:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

AttributeError: 'NoneType' object has no attribute 'logger'

The following code in CODEBK should replicate the issue.

import refinitiv.dataplatform.eikon as ek
ek.set_app_key('DEFAULT_CODE_BOOK_APP_KEY')

from dask.distributed import Client, as_completed
client = Client("tcp://127.0.0.1:41045")

class story:
    def __init__(self, idIn):
        self.id = idIn;
        tmp = ek.get_news_story(self.id, raw_output=True)
        self.headline = tmp['story']['headlineHtml']
        self.story = tmp['story']['storyHtml']

stories = {}
fut = []
currentHeadlines = ek.get_news_headlines(query='Language:LEN', count=10)
for col, row in currentHeadlines.iterrows():
    storyId = row['storyId']
    fut.append(client.submit(story, storyId))

for f in as_completed(fut):
    stories[f.result().id] = f.result()
