Hey. Has anyone faced an absent function issue while overloading inherited function in UUPS upgraded implementation by changing struct in its arguments?

Struct is in separate contract (not inherited) hence there should be no storage slot overlapping.

Im using hardhat for tests

It doesn't matter where the struct is implemented. if you use an UUPS proxy all storage is at the proxy.

Except maybe if the implementation contract does delegatecall, in which case I'm not sure what happens.

The issue was in incorrect ABI generated by hardhat. By calling the function through Contract["function_signature()"] it worked fine. Thanks
