fix(): Transform map (#13655)

**What**
It seems that for some reason the weak map fail in some scenario, but after investigation, the usage of map would not have a bad impact as it will be released after the Distributed transaction if finished. Therefore, falling back to Map instead

NOTE: Waiting for the user feedback as he is also using node 18. We also use the exact same pattern in all our core flows without issues 🤔
