Subscription ID too large?
MorningLit opened this issue · comments
Currently following part 24 of the lottery smart contract series, and can't seem to fit my subscription id into uint64

My subscription id is
58702003961984393061086325485375073005356194632241668487883182282754836008638
on the sepolia chain
Can you create a screenshot of how you got that number? That' shouldn't be possible for your id to be that large.
I clicked on the clipboard icon on id and it also shows up in the URL
I've checked your video and it also looks to be that way I think
And thanks for replying so quickly Patrick!
Managed to solve this by programmatically running the CreateSubscription script Patrick created in this video

Not sure why trying to create a subscription in the UI would result in a very long ID 🤔
eg: https://vrf.chain.link/sepolia/29705503198910972370636457615343113706079550398650684013578130209810340992079

Oh, found out the reason why there is the very large integer, it's because in version 2.5 of chainlink VRF, they increased the size from uint64 to uint256

I see... Thanks for this!
