Help with Authentication failed and not presented in the request when reading a CSV file

Hello,

   I would like to update that it worked when I used the pandas read as  followed:

df = pd.read_csv("abfss://[email protected]/MinhTRanLakehouse.Lakehouse/Files/churn/raw/churn.csv")
df.head()

 However, the Spark read still did not work. It still complaint about authentication failed and not presented in the request when reading a CSV file

{"error":{"code":"Unauthorized","message":"Authentication Failed with Bearer token is not present in the request"}}

Do you know what was missing with the Spark read?

Thanks,

Du

##df = (
##    spark.read.option("header", True)
##    .option("inferSchema", True)
##    .csv("/lakehouse/default/Files/churn/raw/churn.csv") 
##    .cache()   
##)


df = spark.read.format ("csv").option("header","true").load ("/lakehouse/default/Files/churn/raw/churn.csv")
