React和firebase setState'您必须指定“ to”属性'

Question

I tried many hours but can't seem to find what I am doing wrong, I am new to react so I really appreciate your help. I first had an array state of accommodations, then I looped through them with a map function and everything was ok. But after I connected firebase with the project the map function didn't work because firebase was an object so I had to change the map function and assign Object.keys first. Then there is an error that says 'you must specify the "to" property' highlighting me the setState method. I have an image attached to the error. I am so sorry for my poor English, thank you so much for your help

Answer 1

In my case. I used incorrect structure for <Link> component in an other file related to this file.

Wrong structure :

<Link href="...">

Correct structure :

<Link to="...">

after this change, it's ok.
