another edge case here: #1553 (comment)

Could not identify the intended function with name claim, positional arguments with type(s) int,int,int,address,int,(str,str,str) and keyword arguments with type(s) {}.
Found 1 function(s) with the name claim: ['claim(uint256,uint256,uint256,address,uint256,bytes32[])']
