eth_uninstallFilter

Uninstall a registered filter (log filter or block filter).

• Source: framework/src/main/java/org/tron/core/services/jsonrpc/TronJsonRpcImpl.java#uninstallFilter
• Ports: FullNode 8545 / Solidity 8555

The example here must be tested against your own node (e.g. http://127.0.0.1:8545/jsonrpc): filter state lives in a single fullnode process (eventFilter2ResultFull / eventFilter2ResultSolidity). Public gateways (such as nile.trongrid.io) are usually reverse proxies load-balancing across multiple nodes, so two consecutive requests may land on different nodes — the second request will see the filter ID as nonexistent.
