How do I display the value of my keyset field

keyset_key = fields.Json()

	​
def read(self, fields=None, load='_classic_read'):       
	​records = super(InsuranceClients, self).read(fields, load)        	​	​   	​
   for record in records:                                               	​	​if record['keyset_key']:
      	​print("keyset_key - ", record['keyset_key'])                    
   return records

 I want to retrieve the field value in odoo's read function for modification but the field is not displayed in the records
