TypeError: Cannot read properties of undefined (Reading 'map')

Greetings.

Today, out of the blue, my node-red instance got stuck in a crash loop. Upon investigating I've found out it was this node that was crashing node-red.

I've "fixed it" by changing:

this.deviceByIdExt = new Map(response.devices.map(o => [o.serialNumber, o]));

into

this.deviceByIdExt = new Map(response.devices?.map(o => [o.serialNumber, o]));

but someone smarter than me should take a look at it :D
