Do I need to transfer fund to ethereum-bridge contract?
@oraclize-support Do I need to transfer fund to ethereum-bridge contract?
Oraclize Support
@oraclize-support
@hatshu - this may be to do with how to bridge it set up to handle low/zero gas environments. Could you stop the bridge, then in the bridge repository checkout the rsk version of the repo via git checkout rsk and then restart the bridge with the same flags you're currently using. Then we can see if it makes it past that step.
@addios41 - not unless the bridge output tells you to do so when you first start it up. What output do you see when it is first run?

now i see more things in the output of bridge
Oraclize Support
@oraclize-support
@hatshu - okay looks good and that the low price warning is no longer there. Can you try making a query now?
addios41
@addios41
@oraclize-support it works now. I have to restart the ethereum-brige. thank for your support.
@oraclize-support Do we have any log why it got struck?
hatshu

@oraclize-support this is the console now

and this is on remix output, i cant deploy now
Oraclize Support
@oraclize-support
@addios41 - not sure in this case but we're glad it's working now!
@hatshu -that low-balance warning may be ignorable since your network needs no ETH to work. As for why it no longer deploys, that's tough to diagnose from that output. Does it work if you comment out the update() on line 18?
hatshu
@hatshu

@oraclize-support the same error
Oraclize Support
@oraclize-support
@hatshu - Hmmm interesting. Have you tried restarting your whole environment from scratch so that you're working from a clean slate?
hatshu
@hatshu
you mean restart the server, o install bridge again?
@oraclize-support you mean restart the server?
Oraclize Support
@oraclize-support
@hatshu - your entire environment.
hatshu
@hatshu
now works¡¡¡¡¡¡¡¡¡¡¡ thx you¡¡¡¡ rsk will be merged with master?
Oraclize Support
@oraclize-support
@hatshu - turning it off and on again always works! :p And it hopefully will be - a few more tests to ensure it's backwards compatible are required first however.
hatshu
@hatshu
@oraclize-support . I have another question now. Im remix the contract works , I can deploy and when i call getPrice2 i have the correct number, but when I use truffle in visual studio code, the same contract, when i try to deploy with command truffle migrate --network telsius --reset I have this error: Replacing KrakenPriceTicker... Error encountered, bailing. Network state unknown. Review successful transactions manually. Error: The contract code couldn't be stored, please check your gas limit.
Oraclize Support
@oraclize-support
@hatshu - if your setup was working in Remix but not in Truffle it suggests that it's likely a truffle configuration issue that you're having, which is beyond our remit here. Check your configuration carefully from top to bottom.

@praveen2207
@oraclize-support Do I have to pay to use oraclize in a test network?
Oraclize Support
@oraclize-support
@praveen2207 yes, but using testnet eth, so it has no real cost but it helps you to test the exact behaviour you would see on mainnets

@thesachinmittal
@oraclize-support How can a deploy matic on provable?
Oraclize Support
@oraclize-support
Hi @thesachinmittal - whilst we don't have a specific integration with Matic, it does appear to be EVM based meaning our ethereum-bridge here: https://github.com/provable-things/ethereum-bridge is very likely to allow you to use the Provable service with Matic. You can see some examples here of how to use the ethereum-bridge : https://github.com/provable-things/ethereum-examples/tree/master/solidity/truffle-examples
Sachin Mittal
@thesachinmittal
@oraclize-support Thanks.
angela gilhotra
@nglglhtr
@oraclize-support I believe as long as a sidechain is EVM based, it is possible to use Provable using the tool , Ethereum-bridge. Wanted to know if this tool is dapp dependent or network dependent?
I mean, should i be contacting the sidechain developers or build and use my own bridge?
Oraclize Support
@oraclize-support
@nglglhtr - it's network dependent but if the network is EVM based it may well work right out of the box!
angela gilhotra
@nglglhtr

@oraclize-support I'm having trouble when connecting the bridge to matic's RPC, node bridge -H https://testnet2.matic.network

Error:

[2020-02-20T20:54:47.047Z] INFO deploying the oraclize connector contract...
Error: Error: Invalid JSON RPC response: "<html>\r\n<head><title>504 Gateway Time-out</title></head>\r\n<body bgcolor=\"white\">\r\n<center><h1>504 Gateway Time-out</h1></center>\r\n<hr><center>nginx/1.10.3 (Ubuntu)</center>\r\n</body>\r\n</html>\r\n"
@oraclize-support , so you suggest this tool to be run by sidechain network instead of each individual dapp?
Oraclize Support
@oraclize-support
@nglglhtr - does the Matic RPC match the ethereum one. The tool bridges your chain and the Provable service.
angela gilhotra
@nglglhtr
@oraclize-support yeah, the RPC is correct.
@oraclize-support is there a way to make this bridge decentralised?

Hello, I am testing on Kovan and when I look at my query status it says in progress. For last 3 hours. My query is: ce6778e954220e837bc5172b86cbd87e7ff2b549453a431e442a19b43363cb29 When I check it says A correlated Query ID was found, Query ID: a7057eff7dedb9a3043787af1229b2c2d2d0432465e90d489046e0edd534192c and status still in progress. Any reason for that ? https://app.provable.xyz/home/check_query?id=a7057eff7dedb9a3043787af1229b2c2d2d0432465e90d489046e0edd534192c

Hello @sani69654, we are looking into it and will report here once we have any update regarding the issue
Oraclize Support
@oraclize-support
@dani69654 everything looks right on our side, could you please provide the queryid or the txid triggering the query? Thanks
robertmagier
@robertmagier
My transactions were processed after few hours. All of them together. Are you able to tell me what happened and if I should expect such problems on main net ?Thank you.
robertmagier
@robertmagier
Another question. Is there any reason why Oracle will call my callback function twice ? First call gives me random number and then oracle calls __callback again. It fails because I check for it in my smartcontract. Any reason why it is happening ? Thank y ou.
robertmagier
@robertmagier
@oraclize-support ?
robertmagier
@robertmagier
Is anybody here at all ?
Oraclize Support
@oraclize-support
@robertmagier yes, as described in the docs best practices you should use the queryid to prevent any potentially damaging behaviour, so just to control any side effect you should mark a query as processed after the first tx has been confirmed. For instance if a callback takes too long to be confirmed we may broadcast it again. Please see the “best practices” section of our docs ;)
robertmagier
@robertmagier
Ok. That's what I do. I am rejecting second callback. I was just curious if it is normal that you call it twice. Thank you.
@oraclize-support How about this other issue? Yesterday few transactions were not processed for few hours on Kovan network. And then at one point they were processed all togethger in one moment. Can I expect such behavior also on main net ? Is it related to gas price or is it something on your side ?

@oraclize-support I can't test post using test query tool. Is this example working? json(https://api.postcodes.io/postcodes).status {"postcodes" : ["OX49 5NU", "M32 0JG", "NE30 1DP"]} This displays on the website
Oraclize Support
@oraclize-support
@robertmagier we run more experimental code on testnets, I confirm you can expect a much more reliable behaviour on mainnet
Oraclize Support
@oraclize-support
Hi @zhaoyang626, thank you for reporting the issue, the query performed includes some errors which are now being fixed. If you want to try the working request just type this into your terminal:
\`curl -X POST -H 'Content-type: application/json' '[https://api.provable.xyz/api/v1/query/create](https://api.provable.xyz/api/v1/query/create)' -d '{"datasource":"URL","query":\["json\([https://api.postcodes.io/postcodes).status](https://api.postcodes.io/postcodes).status)","{\\"postcodes\\" : \[\\"OX49 5NU\\", \\"M32 0JG\\", \\"NE30 1DP\\"\]}"\]}'`
