Pandas to_sql Error: Invalid column name 'None'

问题

I am using pandas to_sql() to insert pandas's dataframe to sql database, using following snippet:

params = quote("DRIVER={SQL Server};SERVER=%s;DATABASE=%s;UID=%s;PWD=%s"%(config.server,config.database,config.user_id,config.password))
self.engine = create_engine("mssql+pyodbc:///?odbc_connect=%s" % self.params) 

Connection is working fine.

dataframe.to_sql("InvoiceStandardization_InvoiceExtractTemp", con=self.engine, if_exists="append", index=False)

When I tried this it's showing error as :

[42S22] [Microsoft][ODBC SQL Server Driver][SQL Server]Invalid column name 'None'. (207) (SQLExecDirectW)")

I have checked all columns are available in my dataframe which are in database in same order. What could be the possible solution?
