abi: cannot use []hexutil.Bytes as type [0]array as argument

[femtoeu]

I want to execute contract function that requires bytes32[]
I have this array in json:

I unmarshal it into []hexutil.Bytes and when i'm passing this slice into function i get this error:

abi: cannot use []hexutil.Bytes as type [0]array as argument

You should use common.Hash for bytes32. This could use some better documentation and error messages.
