[jurijbajzelj]

• Parity Ethereum version: Parity-Ethereum/v2.0.6-stable-549e202-20180919/x86_64-linux-gnu/rustc1.29.0
• Operating system: Linux 4.4.0-1061-aws
• Installation: bash <(curl https://get.parity.io -Lk) -r stable
• Fully synchronized: yes
• Network: ethereum

Event in question: https://etherscan.io/tx/0x76357a02c8ab0d1b9ab2a4df6f266252d2735b4de7d65a85830c77370bd2de27#eventlog
I'm using _web3py_ to retrieve _Transfer_ events.

event_filter = contract_instance.events.Transfer.createFilter(fromBlock=4800000, toBlock=4800000)
return event_filter.get_all_entries()

actual behaviour - events returned (I'm getting this using Parity)
[]

expected behaviour - events returned (I'm getting this using geth)

Hey, have you double checked with https://wiki.parity.io/JSONRPC-parity-module.html#parity_chainstatus that the range of blocks you're looking for are actually present on your node?

$ curl --data '{"method":"parity_chainStatus","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST <node_endpoint>
{"jsonrpc":"2.0","result":{"blockGap":null},"id":1}

It's quite likely this and https://github.com/paritytech/parity-ethereum/issues/9916 are the same issue. Closing as duplicate, and we'll track this there 👍
