Why is my recordId undefined ? LWC

Question

Problem : I have my LWC inside an Order page, but can't retrieve the recordid which is undefined.

Here's a screenshot of my LWC:

• the header is the standard part with data stored in SF
• below the Collapse/Expand link, is custom and I retrive data from an API without storing it in SF

Here's my code:

JS file:

import { LightningElement, track, api } from 'lwc';
import getCustomerOrder from '@salesforce/apex/icCTRLCustomerOrder.getCustomerOrder';

export default class IcOrderDetails extends LightningElement {

@track customerOrder;
@track doDetail;
@track paymentDetail;
@track doDetails;
@api recordId;
connectedCallback(){
    this.fetchOrderDetails();
}
fetchOrderDetails(){
    //getCustomerById({})
    console.log('recordId ', this.recordId);
    let customerOrderNumber = 'XXXXXX';

    getCustomerOrder({customerOrderNumber:customerOrderNumber})
    .then(data => {

        this.customerOrder = data;
        this.doDetails = data.paymentDetails;
        console.log('this.customerOrder ', this.customerOrder);

        for(let i = 0; i < data.doDetails.length; i++){
            this.doDetail = data.doDetails[i]; 
            for(let j = 0; j < data.doDetails[i].doLineItems.length; j++) {
                this.doLineItem = data.doDetails[i].doLineItems[j]; 
            }

        }

        for(let i = 0; i < data.paymentDetails.length; i++){
            this.paymentDetail = data.paymentDetails[i];
        }

    }).catch(error => {
        window.console.log('callout error ', JSON.stringify(error));
    })
}

}

I've looked at multiple posts but already did the solutions that were given. What did I miss ?

ETA complete JS file

Answer 1

I got it. I had everything right but was trying to retrieve the recordid from the wrong component.

My component is inside another and it's this one which is on the record page.

Hope I can help someone so they won't waste as much time as me today...
