Whenever this code is executed, the following error is displayed:
Cannot read property 'filter' of undefined contrat: Contrat[];
gpss: GPS[];
homeboxp: HomeboxP[];
sensors: Sensors[];
homebox: Homebox[];
getProductName(productid: string) {
const [filteredProd] = this.contrat.filter(pt => pt.contrat_id === productid);
const [filteredProdG] = this.gpss.filter(pt => pt.gps_id === productid);
const [filteredProdhbp] = this.homeboxp.filter(pt => pt.homeboxpackage_id === productid);
const [filteredProdh] = this.homebox.filter(pt => pt.homebox_id === productid);
const [filteredProds] = this.sensors.filter(pt => pt.sensors_id === productid);
if (typeof filteredProd !== 'undefined' && productid === filteredProd.contrat_id) {
return filteredProd.contratdesc;
} else if (typeof filteredProdG !== 'undefined' && productid === filteredProdG.gps_id) {
return filteredProdG.gps_serial;
} else if (typeof filteredProdhbp !== 'undefined' && productid === filteredProdhbp.homeboxpackage_id) {
return filteredProdhbp.serial_number;
} else if (typeof filteredProdh !== 'undefined' && productid === filteredProdh.homebox_id) {
return filteredProdh.serial_number;
} else if (typeof filteredProds !== 'undefined' && productid === filteredProds.sensors_id) {
return filteredProds.sensor_serial;
}
}
I am seeking suggestions as to what could be causing this issue. The functionality seems correct, but the error persists.
Your insights are greatly appreciated. Thank you!
