Hi @Truciolonyc, I can’t really help here… These keys serve to have access to on chain datas needed for the auto task to do the job. i try with the script given by @bolo. At first glance it’s seem working but i encounter several time this error :

Edit : I’ve erased all other references than ETHERSCAN (Alchemy & infura), since then. No more previous errors

Edit 2 : same error just happened.

Did you change this part ?

 const provider = ethers.getDefaultProvider("mainnet", { 
etherscan: "xxxxxx",
alchemy: "xxxxx",
infura: {
  projectId: INFURA_PROJECT_ID,
  projectSecret: INFURA_PROJECT_SECRET,
},
  })

Yes I know, I’ve putted my ethers an apy key only. It is mandatory to have an infura key too?

I just create an APY Key with infura. I put it in the script with my etherscan and alchemy one. I will see

The modified script looks good to me, @bolo! Thanks for setting it up!

HI,

I did enther my infuria Key, I dont have an Alchemy nether and Ethescan…are those mandatory? most of the jobs are process successfully. Should i start seen some credit?
Again, i’m navigate in a totally new world, quite fascinating I should say, forgive my ignorance, but I really want to see if I can make. I will start studying soon…promise. :))

Hi, I have followed the guidance and it works well now, just an amatuer question, How long will it take to see work completed?

48

I asked the same question. check the answer.
https://forum.openzeppelin.com/t/how-to-use-infura-api-project-id/4471/9?u=bolo . It’s not.

Thanks! You are great help to me

All worked fine…but every job shows not workable? is it normal?

51

@spalladino got the same scenario. all jobs shows not workable even with periodicity of 1 minute.

Hey Bolo, it’s possible that competition is currently so fierce that it’s difficult to land any jobs. There are apparently 600+ registered keepers in the network at the moment. You may need to wait until the network stabilizes and some keepers drop or more jobs come up. I’m curious though if there are any official stats of the state of the keeper network…

53

like that? https://keep3r.live/
it’s look like always same guys who are able to claim the rewards.

55

Hey @bolo, thanks for replying. I have an error or is it a bug in the

Keep3rV1Oracle
It throws an error as the status is workable.
the error is
Error: too many arguments: passed to contract (count=1, expectedCount=0, code=UNEXPECTED_ARGUMENT, version=contracts/5.0.2)
at Logger.makeError

Thanks again.

56

Could someone tell me what the error " failed to meet the quorum" mean?

Ty

57

Did you use your own key? Because when i use that the error goes, but i got another error which I explained above.
I think this means something related to gas estimation but it should be fixed if you use your own key in the script. As @bolo mentioned in the previous comment.

58

Yes I am using my own keys.

Do you get this error? Then How do you fix it?
Error: too many arguments: passed to contract (count=1, expectedCount=0, code=UNEXPECTED_ARGUMENT, version=contracts/5.0.2)
at Logger.makeError (/opt/nodejs/node_modules/@ethersproject/logger/lib/index.js:179:21)

try that. https://gist.github.com/bolom/8e159ea4a30eb50d8f1f7c1a20e3ef07#file-gistfile1-txt-L42

Sorry for disturbing, but the problem is not about gas estimation it is about Contract argument.
specifically the error is the following:
> INFO Keep3rV1Oracle is workable

2020-11-10T18:10:47.666Z	ERROR	Error: too many arguments: passed to contract (count=1, expectedCount=0, code=UNEXPECTED_ARGUMENT, version=contracts/5.0.

Only happens when Job is workable.
thanks so much for your quick reply @bolo
