Issues with the Binance Archive Node

Derked · December 8, 2021, 3:04pm

Hello. I’m searching for past events using ethersjs query filter on the Binance archive node. The event I’m searching for happens every 10000 blocks, but when I send the query like so,

  let events= await contract.queryFilter(filter, -10000, "latest");

I always an error with reason:‘bad response’, code: “SERVER_ERROR”, and body: “The request failed with status code 503”.

Any guidance is appreciated, thanks.

can you provide a minimal sample code that reproduces this problem?

FWIW I know the env reads the archive node url correctly because it’s displayed in the error message I receive.
