Description

I am hitting an expect condition when building a ContractCall from abigen-generated code.

Building the ContractCall:
https://github.com/PeggyJV/gravity-bridge/blob/69d40539a0d8f68ee2a82857462d9558d5cdfa9b/orchestrator/ethereum_gravity/src/valset_update.rs#L132-L146

The error:

The application panicked (crashed).
Message:  method not found (this should never happen): DecodingError(InvalidData)
Location: /app/gravity_abi/src/gravity.rs:278

The JSON used to generate the function:

The code used to generate the file:

@mattsse this seems to be an abigen edgecase, although it seems weird given that the function signature is "simple"

[gakonst]

Should be fixed in #613
