MetaMask web3 instance doesn't return events/logs

[bwheeler96]

I can't get logs from my contract. The following code works fine with the default web3 implementation that comes with truffle:

contract.MeEvent({}, { fromBlock: 0 }).get((err, data) => console.log(data))

But when I run the same code in a browser using the MetaMask version of web3, nothing happens. The promise never returns, and nothing is ever even sent to the network.

For example in the truffle web3 instance, the following requests are logged by testrpc:

eth_newFilter
eth_getFilterLogs

But when using the MetaMask implementation, nothing is even submitted to the testrpc instance.

I read the compatibility guide and am following it pretty closely. I can send transactions and call contracts just fine. I simple can not filter events.

The web3 version MetaMask is injecting is 0.20.2 and the version that truffle builds with is 0.16.0. Hopefully web3 doesn't have any breaking changes in minor versions

As an update to this issue: The problem was caused by faulty network switching within MetaMask

See this stackoverflow: https://ethereum.stackexchange.com/questions/28747/cant-retrieve-event-logs-with-metamask-web3

I quit my browser and reopened my site, then everything worked. I'm happy to help out on either:

1. Adding logic to throw or warn when this happens (a timeout could probably be useful)
2. Fixing the network switching issue

Cheers,

Brian

Also having this same problem on version 3.11.2

To be a bit more specific, MetaMask doesn't return any new events after the specified block number only when watching a specific contract address. If I watch without specifying a contract address, everything works fine

This works as expected, for events before and after someBlockNumber:

web3.eth.filter({fromBlock: someBlockNumber}, function(e, r) {});

These work for events on someBlockNumber, but not for any events created after someBlockNumber:

someContract.SomeEvent({}, {fromBlock: someBlockNumber}, function (e, r) {});
web3.eth.filter({fromBlock: someBlockNumber, address: someContract.address}, function(e, r) {});

Having same issue, my Dapp is not receiving events anymore (using Ropsten).
About 3 weeks ago everything was working fine.

@Overtorment various combinations of quitting and reopening your browser, toggling networks back and forth, and other hack voodoo wand waving seem to do the trick. Good luck

Is there any news about this issue ? Because I am still stuck with Metamask not getting any events from my contracts..

[nteymory]

Still having the same problem on 3.12.0

[GuigsEvt]

Do you know if it is working on older version ?

I have the same issue. Events are not being received by my application when using metamask (it works fine using Web3 connected to local RPC or Mist). It does not matter if I'm using one of the test networks or I'm connected to a local RPC server through the extension.

Is there a version of metamask that resolves this issue? Quitting and restarting my browser didn't do it. p.s. it works just fine without metamask (fallback to local node)

@rawadrifai try version 3.11.1 you would have to load it manually into the extensions list and there might be some other bugs in it as well. This was the version that fixes events/logs but introduced basic use errors.

I have 3.12.0 and it's working now. thanks.
