Error while making the address's indexed in events

[shivam0x]

Hi,

I've a contract in which I've events with addresses. Everything(tests) is working fine. But as soon as I make the addresses in event as indexed I get the following error:

Error: data out-of-bounds (length=32, offset=64, code=BUFFER_OVERRUN, version=abi/5.0.9) at Logger.makeError (node_modules/@ethersproject/logger/src.ts/index.ts:205:28) at Logger.throwError (node_modules/@ethersproject/logger/src.ts/index.ts:217:20) at Reader._peekBytes (node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/coders/abstract-coder.ts:184:24) at Reader.readBytes (node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/coders/abstract-coder.ts:198:26) at Reader.readValue (node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/coders/abstract-coder.ts:205:36) at AddressCoder.decode (node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/coders/address.ts:28:45) at /Users/Project/node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/coders/array.ts:108:31 at Array.forEach (<anonymous>) at Object.unpack (node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/coders/array.ts:89:12) at TupleCoder.decode (node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/coders/tuple.ts:58:41) at AbiCoder.decode (node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/abi-coder.ts:119:22) at Interface.decodeEventLog (node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/interface.ts:478:47) at Interface.parseLog (node_modules/@ethersproject/contracts/node_modules/@ethersproject/abi/src.ts/interface.ts:567:24) at assertArgsArraysEqual (node_modules/@ethereum-waffle/chai/dist/cjs/matchers/emit.js:38:55) at tryAssertArgsArraysEqual (node_modules/@ethereum-waffle/chai/dist/cjs/matchers/emit.js:54:20) at /Users/Project/node_modules/@ethereum-waffle/chai/dist/cjs/matchers/emit.js:66:13

Solidity code:
event ContributorContributed(address indexed contributor, uint256 amount);
emit ContributorContributed(_sender, _value);

If in the above event I remove the indexed keyword then tests are working fine.

This is not happening with all the events but most of them.

My Test code:
await expect(owner.withdrawRandomAssets(randomToken.address, false)) .emit(contract, "RandomAssetsWithdrawn") .withArgs(owner, randomToken.address, 5000)

Not sure if this is related to #992 (unable to parse events with indexed parameters if contract compiled with solc 0.4.x), but try with latest version of ethers and see if this is still a problem.

[yuetloo]

Hmmm...You are using the latest version of abi. 5.0.9.

[shivam0x]

Yes and even solidity 0.7.0.

Can you provide a transaction hash of a transaction that is causing this issue?

I don't quite know what that .emit is doing? Is that part of a test framework? Perhaps it isn't encoding things properly for the indexed fields (which get placed in topics, not the data).

[shivam0x]

@ricmoo I'm getting this error while running tests itself so no transaction hash available for this.
I'm using buidler and waffle for testing to .emit is used for testing purposes to check if the event is getting emitted or not.

[zemse]

If it is possible for you to deploy the contract on some testnet using remix and do this particular transaction that emits this log, pls share the tx hash as it will be easier to debug quickly.

[ricmoo]

I think this might be a bug with how the .emit works in buidler or waffle, or there is some other way in those projects to specify which methods are indexed...

Pinging @alcuadrado, @marekkirejczyk and @sz-piotr.

Can this be related? NomicFoundation/hardhat#1048

[ricmoo]

That seems like the issue here. :)

[shivam0x]

Sure, I'll resume this issue in hardhat repository then.
Thanks everyone :)
