MetaException(message:Unable to fetch mwc token)

[nmadwani]

I get MetaException(message:Unable to fetch mwc token) when I use variables.

person_df = spark.sql("SELECT DISTINCT P.id FROM `{silver_database_name}`.`Person` AS P")

if I use lakehouse name instead it works, please suggest

Hi,

This was due to incorrect string interpolation.
