        this.subsidyId = this.recordId;
        console.log('in connected callback, the record id: ', this.recordId);

and the result in the console is:

in connected callback, the record id:  undefined

 Subsidy Id: {subsidyId}

and it comes up empty.

The xml:


What could I be doing wrong?

I noticed the following warning in the docs (here: https://developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.use_record_context)

but I don't understand what that means. What is explicit record context?
