Does mutate ignore null value since 1.0.0

[jacklimwenjie]

Just asking out of curiosity, my project has a bug that appeared to be magically "fixed" after upgrading the swr package to version 1.0.0.

However, after a deeper inspection, I found the bug is still there.
The bug is caused by mutating a cache with a null value, causing a downstream component that expects the cache value to be an object and access one of its properties to crash.

On the swr package version 1.0.0, the mutation with a null value now keeps the previously cached value, so the downstream component no longer crashes.

Is this something intended?

That sounds like a regression, you should be able to mutate a resource to null. I'll change this discussion to an issue for further investigation.
