Web3.js: ENS Error on Kovan

[hbarcelos]

Expected behavior

Since I'm not using ENS for anything, there shouldn't be an error.

Actual behavior

Upon initialization, I get the following error:

18:42:52.381 Uncaught (in promise) Error: ENS is not supported on network kovan

Steps to reproduce the behavior

1. Connect to web3.js throught MetaMask injected provider pointed to Kovan.

Perhaps, this may help you to find a workaround:
I'm a huge fan of ens and my dapp needs it heavily. Someone asked for ENS2 on kovan and my tool needed it too, therefore, I did an (experimental) installation on kovan at https://kovan.etherscan.io/address/0xb66b2f307b6e46a6d038a85997b401ae87455772#code and https://kovan.etherscan.io/address/0x7966398e99a60c7b3465a394b22c0b5ce1012ec9#code .
I don't know if ENS 2.0 will be officially available on kovan, therefore I did it by myself in the meantime.
I know, this may not directly help you with your web3.js problem. Peter

Looking into this.. I know Metamask uses 0.9.0^ so I'll have to see what exactly is causing this...

[hbarcelos]

Additional info:

The last version where I don't see this error is 1.2.6, any version >=1.2.7 throws the error above.

[GregTheGreek]

Do you mind providing a code snippet? I'm having a hard time reproducing this error because metamask doesn't inject the web3 api anymore.

[zemse]

I have seen similar errors in ethers.js if I enter invalid address. Though it's a different lib, just trying to help if this solves the problem.

@GregTheGreek there's no snippet really, it's just:

const web3 = new Web3(window.ethereum);

Then if I interact with any contract, I see the error.
However, none of my contracts come nowhere near ENS.

ah ok, let me dive into this

[GregTheGreek]

Im unable to reporduce this on v1.2.3, can you confirm?

[hbarcelos]

I only see this issue on version >=1.2.7.

I'm currently locked in 1.2.6 because of an unrelated problem and there's no issue.

[GregTheGreek]

Sorry I'm not sure why i typed 3... I meant to say v1.2.11
