If you don't care to render anything, then you can also just optional chain that map

Did you mean to make it
Promsie<ReadonlyArray<Subscription>>?conscious-sapphireOP•2y ago
No, where is it being made. readonly?
continuing-cyan•2y ago
Well readonly doesn't matter, I just prefer it. Changing line 12 from
Promise<Subscription> to Promise<Array<Subscription>>conscious-sapphireOP•2y ago
That takes the error away! thank you
Now there is a different error but i can resolve this

@troywoy I have one more question maybe you can answer
If i am mapping threw is there a way to style the "title" different to have a different bg color for each
continuing-cyan•2y ago
You can do that however you want. Try adding style, or
className would probably be better, onto your SubscriptionCard
