Get number of all the past events using ethers v5

Question

I am writing an integration test and I need to get the number of all the past events using ether.js. The issue I am having is that it seems like I receive only 1 event even though there should be 4 in total. Here is the code I use:

  const provider = new ethers.providers.JsonRpcProvider(TEST_JSON_RPC)
  const loanVaultFactory = new ethers.Contract(
    address,
    abi,
    provider.getSigner(0)
  )
  let events = loanVaultFactory.filters.LoanVaultCreated()
  console.log(events)

And this is the output:

{
  address: '0x27e8A5B8Af57aEE27A33247D867ED52173876791',
  topics: [
    '0x2c80e53ce4a0770abb7d3436ea6bc5ff59702f84b0d9378b4c58cc59e4618042'
  ]
}

I would expect there to be 4 items in the topics list. Am I doing something wrong with the filters? Thank you

The filter method doesn't return the events but the filter object. To get the events you have to pass the filter to the contract.queryFilter method:

  const contract = new ethers.Contract(
    address,
    abi,
    provider.getSigner(0)
  )
  let eventFilter = contract.filters.ContractEvent()
  let events = await contract.queryFilter(eventFilter)
