Obscure error message due to the missing device

[m4tiz5zktonj]

If some device from manifest.xml is missing - either does not exist (e.g., old preview versions of devices) or is not downloaded yet via SDK manager, the following error occurs:

[{
	"resource": "/<unknown>",
	"owner": "analysis",
	"severity": 8,
	"message": "Cannot destructure property 'fnMap' of '(intermediate value)' as it is null.",
	"source": "[pmc-analysis]",
	"startLineNumber": 1,
	"startColumn": 1,
	"endLineNumber": 1,
	"endColumn": 1
}]

I'd like it to be "Device 'someDevice' doesn't exist" or something like that.

It can be reproduced by adding no longer existing <iq:product id="epix2pro47mmsystem7preview"/> to manifest.xml.

When exactly do you get this error? I'm not getting it even if I make up products.

Sorry, I don't remember details of the original case - I opened someone's project from the GitHub and got that error.

Now I can reproduce it only when all products from the manifest are missing or not exist:

<iq:products>
    <iq:product id="epix2pro47mmsystem7preview"/>
    <iq:product id="notExistingProduct"/>
</iq:products>

If I add at least one existing and downloaded device, this error disappears.
