Error with fundamental_and_reference.Definition data api

augusto_krappa

With the code below:

df_chunk = fundamental_and_reference.Definition(

                        universe= tickers,

                        fields = ['TR.CLOSEPRICE.date','TR.CLOSEPRICE','TR.Volume'],

                        params = {"SDate": 0, "EDate": -756, "FRQ": "d"})

why is it raising error?

Error processing chunk 1: Definition.__init__() got an unexpected keyword argument 'params'

Thank you for reaching out to us.

It should be the parameters, not params.

|  parameters : dict, optional

 |      Fields global parameters.

You can use the help(fundamental_and_reference.Definition) command to verify its valid parameters.
