     "$or":[
             name: { $regex: new RegExp(`^${company.name}$`, 'i') },
             company_code: { $regex: new RegExp(`^${company.company_code}$`, 'i') 
            ]
}
}
cModel.find(filter, function (err, docs) {
                        if (docs.length) {
                            result.error = "Name already exists: " + company.name;
                            console.log("Name already exists", null);
                            let resp = api_respose.getSuccessResponse(process.env.WEB_URI, result.error);
                            resolve(resp);
                        }
