What was wrong?

I'm unable to parse this event from this contract. Getting the following error:

order = w3.eth.contract(address='0xCd81398895bEa7AD9EFF273aeFFc41A9d83B4dAD', abi=getAbi('0xCd81398895bEa7AD9EFF273aeFFc41A9d83B4dAD'))
event_filter = order.events.LogCanonicalOrderFilled.createFilter(fromBlock=9936332)
event_filter.get_all_entries()

/usr/local/lib/python3.7/site-packages/eth_abi/registry.py in find(self, type_str)
     89             raise NoEntriesFound("No matching entries for '{}' in {}".format(
     90                 type_str,
---> 91                 self._name,
     92             ))
     93 

NoEntriesFound: No matching entries for 'tuple' in decoder registry

How can it be fixed?

Could be related to #829.

Can you provide the output from pip freeze so we can see versions of your dependencies.

[recmo]

pip freeze (Sorry for the mess, this is my Jupyter Notebook which doesn't run in a virtualenv)

IIRC, someone brought this up in chat recently, too. My first guess was an old version, but like @recmo, they had recent-enough libraries.

#1235 is what added tuple support generally, so really #829 should have closed. (Though clearly there's a new, specific problem here)

I do notice that this PR only adds tests for tuples at method arguments and return values. I don't see any tests for tuple-typed events. So the first step seems like adding a test of parsing an event with a tuple-typed log value.

Presumably that will fail and then we can get this fixed up.

[KaiRo-at]

Maybe related to #1569 as well (arrays there, not tuples, but otherwise I guess similar)?

[kclowes]

I'm pretty sure this is also the same problem as the one in #1621. I am going to close #1621, but want to leave #1569 open because I'm not sure that's exactly the same problem, even though it does look similar.

[dfinzer]

Running into this as well. Any good workarounds?

[rexeee]

So can not support ABIEncoderV2 to enable structure-type parameter in event?

[alexisVandewalle]

I have the same issue when i try to parse an event wich takes a struct as parameters

For anyone struggling here, applying the patch from #1484 works for me.

Glad that got your case working! A test I would definitely want to see before marking this as resolved is tuples-in-tuples. It's not obvious that #1484 handles that case.

collapse_if_tuple handles nested tuples.

Hello there! I just got a similar issue today. Is there a workaround? Should I use a fork of web3.py?

[fselmo]

Going to close this since #2211 should fix this particular example
