Hello Guys.
I'm trying to use 'Sleep' adapter but requests executes immediately without deley.
//ROPSTEN
address _oracle = 0xA3Ce768F041d136E8d57fD24372E5fB510b797ec;
bytes32 _jobId = "00364325dafb410bbdadd7d79e69eab5";
function _requestSobr(uint delay) private {
Chainlink.Request memory req = buildChainlinkRequest(_jobId, this, this.fulfill.selector);
req.addUint("until", now + delay);
req.add("get", "https://api.loanscan.io/v1/reference-rates/current/Sobr?tokenSymbol=DAI");
req.add("path", "DAI");
req.addInt("times", 100000000);
sendChainlinkRequestTo(_oracle, req, LINK);
}I found an accepted bug, does it works today or am I doing something wrong?

Hi all. I'm looking at implementing an ETH:USD price feed in my Ethereum dApp via the Chainlink Aggregator template.
I hear Chainlink prices are updated every 10 minutes. Are oracles synchronized with their price updates, or do they update on their own schedules? I'd like to ideally minimise gas and only request a new price when oracles have updated their data.
1 - are there any research grants available for Chainlink?
2 - are there any in-depth docs available other than whitepaper, official docs and codebase? Especially about the aggregating process on-chain and/or external adapters. Is there a way to get in touch with someone from inside Chainlink to discuss further details - I'm doing research in that area. Would also be great to know which parts of the whitepaper are still valid - e.g. there is a part about Chainlink's goal to combine Trusted Execution Environment in this aggregation process.
for this function:
function requestEthereumPrice(address _oracle, bytes32 _jobId, uint256 _payment)
Has anyone ran into this before ?
Hi Guys,
I use Chainlink to request data and then save it in a local variable. This variable is then assigned to an array. Unfortunately the data assignment to the array is not synchronous, because I get the result from Chainlink a bit later.
What can I do so that only when I receive the data from Chainlik, is it assigned to the array?

where is libpq behavior defined. Seems to me since no user is specified in the DB url its using my shell login. I'll try it with the chainlink user
