22:22:27@gitter_reterik:matrix.orgreterik (Gitter) I have a chainlink node running alongside geth and I cannot figure out how to send an erc20 token to another account the curl command looks like this and returns body=FAILED TO READ BODY

I have a chainlink node and a quorum local node running, I could create a job and had successful job executions that hit sample API for 0.4. solidity version contracts, however as I used 0.5 version solidity chainlink contracts , the chainlink-node fails to parse the tx logs

Hello, I'm trying to deploy a TestConsumer contract to Ganache via Remix but I get this error:

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
"message" must be a nonempty string.

It deploys on Ropsten without any problems. Would there be a difference between Ropsten network and Ganache? I've also set my hardfork version to byzantium
The code I'm trying to compile is this https://raw.githubusercontent.com/smartcontractkit/chainlink/master/examples/testnet/contracts/TestnetConsumer.sol

22:35:06@gitter_fourohfournotfound:matrix.orgfourohfournotfound (Gitter) @harrumphharrumph ah, yea I guess so I submitted my node to that 4months ago

20:46:46@gitter_acoutts:matrix.orgAndrew Coutts (Gitter) Hi - I just created a bitcoin adapter for Chainlink. So far it supports querying the current block number but I will soon implement other functionality like querying transactions and addresses. https://github.com/acoutts/chainlink-bitcoin-adapter
20:47:12@gitter_acoutts:matrix.orgAndrew Coutts (Gitter) I was hoping to get it added to this page here:
https://github.com/smartcontractkit/chainlink/wiki/External-Adapter-Registry
20:50:56@gitter_thodges-gh:matrix.orgThomas (Gitter) Good work! Let's move technical discussion to our Discord, here: https://discord.gg/aSK4zew
You'll be able to reach more node operators and developers there.

12:43:18@gitter_ivanzakharov:matrix.orgИван (Gitter) It seems Ropsten' ETH/USD Aggregator contract has been redeployed at 7th of Jan. So, the services using old version at 0x0Be00A19538Fac4BE07AC360C69378B870c412BF should update the aggregator address to 0x8468b2bDCE073A157E560AA4D9CcF6dB1DB98507. Also naming of variables has changed, now the price is stored in 'latestAnswer' variable, not in 'currentAnswer'.
But actually it updates very slowly, last update has been performed about 30 hours ago. Is it possible to speed up updating?
Can we expect redeployment of Mainnet contract?

09:57:00@gitter_theoturner:matrix.orgTheo Turner (Gitter) Hi folks, am I right in understanding that buildChainlinkRequest()/sendChainlinkRequest() implements a callback, so computation of my Solidity contract will not proceed until the job has been fulfilled?
10:00:00@gitter_theoturner:matrix.orgTheo Turner (Gitter)

e.g. if I take the requestEthereumPrice() example in the docs, and do this:

requestEthereumPrice();
uint256 x = currentPrice;
requestEthereumPrice();
uint256 y = currentPrice;

will x and y have different values (assuming the price changes in the time between requests)?
