Issue using createContractEventFilter with NextJS app directory

[neokry]

When using createContractEventFilter in NextJS app directory getFilterLogs occasionally throws with a filter not found error. Anyone else running into an issue like this? Not sure if its an issue with viem, alchemy, or next.

Mind putting together a minimal reproducible example? Happy to take a look.

Having issues creating an example on stackblitz. only seems to really be reproducable when I deploy on vercel and it always seems to error the first call after deployment (not sure how helpful this is). It seems to be a viem error though because switching back to ethers for the log filter works with no issues.

This is how the logs were being queried if that helps: https://github.com/neokry/builder-reasons/blob/e76a60424c0db70a292077fcbc9bdb0cc9b89b95/data/eth/proposal.ts

Hmm, I seem to be creating the filter and getting logs fine... Would you be able to create a minimal reproduction like mine? Below is my working example:

You might need to specify a startBlock for the filter to work

yes using startBlock fixed one of my issues but now running into issues even with startBlock set
