I tried to update Department field in Salesforce Contact object. I got this error response : "INVALID_FIELD_FOR_INSERT_UPDATE Unable to create/update fields: Name. Please check the security settings of this field and verify that it is read/write for your profile or permission set".
When I tried the Opportunity object(Fields : Amount, stageName), the update succeeded.
I checked the field security levels on both objects' fields. Security levels are same but I am not able to update the Contact object. Could anyone help me with this issue? Stage(opportunity) field access levels - Department(Contact) field access levels
