eth_getFilterChanges has unclear input and return values

[digitaldonkey]

I ran into some issues which seem important to be aware of when using the Schema with

eth_getFilterChanges": [["Q"], ["FilterChange"], 1],

Input "Q" is a different Q than others.

is IMHO not correct if you see Q as a 32byte padded number.
Q in this specific case is actually unpadded.

Return values are not correctly represented.

There are two different return types

• Filter added with eth_newBlockFilter (block hashes) -> returns [D32]
• eth_newPendingTransactionFilter (transaction hashes) -> returns [D32]
• Filter added with eth_newFilter -> returns [FilterChange]
