Thanks for the PR, could you get a minimal reproduction of this issue so we can have a test case for it?

@shuding - I hope this one is quite self-explanatory. I think the vercel team has to decide if those action properties should be considered reserved/read only or if other libraries can use the same properties. Or else just clarify the way this is supposed to work, generally.

I arrived at this issue because tRPC is in some cases providing its own ID, leading to Cannot redefine property: $$id. Depending on what you decide here, I can report back to the package authors that this needs to be changed, or merging this fix will restore the behaviour of NextJS < 13.4.19.
