When I am initializing new chainlink node after I enter and confirm new password, somethimes input to enter API email appears but somethimes not

Been having lot of trouble with this

Not logs and explanations nothing

The node just quits

But sometimes Enter API email appears even though commands are the same

I want to add a postgresql database as an external adapter to one of the nodes, I want to know that is it even possible or not?

@fm-b

can I have a private chainlink(instance of chainlink core with different cintract addresses)?

hi everyone, is chainlink alarm clock available now?

i tested the function of chainlink alarm clock before, but now it's not working.

Only data APIs can be used as external adapters. Rest APIs ... 2. private chainlink with diff. contract address? I dont understand. Are you asking if you can create a chainlink node that only you can use, yes. Simply do not add your node to marketplaces and no one but you will use it. If you want different contract address, you need a separate node if i understand your questions correctly.

i tested the function of chainlink alarm clock before, but now it's not working.

idk, ive never tested it but there are plenty of clock apis you can use in your smartcontracts . If you tested the alarm clock adapter previously successfully but now it does not work, could you kindly post error message to further assist you?

check the official docs, https://docs.chain.link/docs/miscellaneous, scroll to bottom and follow steps to config your login credentials to auto login. post screen shot/error code if u still run into trouble

i see no error, how are you making request? Check transaction on ropsten to confirm. Have you tried deploying a consumer smart contract to test fulfillment capabilities?

When making a requestEthereumPrice() from TestnetConsumer.sol to my oracle the 1 Link fee/request is arriving and the transaction is executing, but the activity is not being recorded on the GUI and ETH price does not update (remains at 0) when running currentPrice() on TestnetConsumer.sol.

your node should never be empty of eth....send eth to your node.

Helios

@Zhang-777

you mean chainlink alarm clock doesn't work if contract(node) have no eth, right?

then can you send me test eth to my contract?

Hello everyone, why can I not get any LINK from chainlink ropsten faucet?

Corey Lin

@CoreyLin

The faucet shows "Your request was successful! View your transaction here.", but actually the transaction doesn't exist in ropsten etherscan, and my address didn't receive LINK.

@CoreyLin

When will ropsten link faucet be fixed?

Corey Lin

@CoreyLin

In chainlink, there's a core adapter in the chainlink called EthBytes32, and the adapter converts the string into solidity's bytes32 format, but this leads to the question: What if the string you're trying to retrieve from the external API(e.g. a weather API for a city) through the chainlink is more than 32 bytes? I haven't found a adapter that can handle more than 32 bytes string, so how to address this length limit problem? Is there an adapter to convert string to bytes instead of bytes32?

I am facing the same issue Can any one provide ropsten link token

this is my address

Hey all. When I try to start my node on Ropsten I get two errors...

[ERROR] unable to lock ORM: dial tcp 127.0.0.1:5432: connect: connection refused logger/default.go:139
[FATAL] Unable to initialize ORM: dial tcp 127.0.0.1:5432: connect: connection refused
unable to open for gorm DB

my DB URL 👉 DATABASE_URL=postgresql://MY-USER-HERE:MY-PASSWORD-HERE@10.84.96.3:5432/chainlink-ropsten-instance
my run call 👉 cd ~/.chainlink-ropsten && docker run -p 6688:6688 -v ~/.chainlink-ropsten:/chainlink -it --env-file=.env smartcontract/chainlink local n

I can't connect to the DB via datagrip either for some reason... ???
Anyone help me out?

Hi Beau maybe try echo again like to readd the database? I noticed testing with Ropsten the .env file

how can i get multiple return variable in a single chainlink query ?

@vcollabca

Hi community. Trying to test my chainlink node job on Kovan using test consumer leftover on this page: https://docs.chain.link/docs/fulfilling-requests. My node deploring was successful. Test consumer deployment was successful. And the requestEthereumPrice showed success too. But the currentPrice shoes zero. I checked my job runs. There are none.

What could I be doing wrong?

Sagar Chaurasia

@Chaurasiasagar01

Hi , i need to convert eth address returned in string format to address , what is the best way to do it (inside smart contracts)? example - "0x0000000000000000000000000000000000000000" to 0x0000000000000000000000000000000000000000

Hello everyone, I'm new in smart contract programming and I want to write a smart contract for compensation, if customer did not receive the service correctly the smart contract should transfer amount of eth from provider wallet to customer wallet, can I do sth like this? and what else if there was not enough eth in provider's wallet?

Hello, is their support for tls1.3 ? I watched a talk regarding BLS Signature as well, is that slated to be included in any of the query and proof workflows?

Brian Soule

@briansoule

Where can I see a list of the oracles on testnets?

hershkoy

@hershkoy

@briansoule you have https://market.link
If you need a node for hosting an external adapter on kovan testnet, I can help

Brian Soule

@briansoule

Thanks@hershkoy market.link only seems to show mainnet oracles, am I missing something?

Wait I see the network dropdown, this is great

Brian Soule

@briansoule

@hershkoy How do I infer the AggregatorProxy contract for an aggregator? Do not all oracles have a proxy yet?

hershkoy

@hershkoy

I am not sure. To be honest the Aggregators is not something that I tried until now, so I don't know how they work. You can try to ask in the discord community if you don't get an answer here

There is also the linkpool community in telegram, you can try to ask there

Brian Soule

@briansoule

Thanks

Brian Soule

@briansoule

Does anyone know how to get added to an oracle to avoid the checkAccess() errors? It seems to be a core part of an oracle api but I can’t find any documentation about it
