Why this type can not be decode?

https://substrate.stackexchange.com/questions/6219/why-this-type-can-not-be-decode

I didn't get any helpful answers from StackExchange.
So, I open an issue here.
Sorry for this.

Is there any way to decode this? Thanks.
I don't know how to make my front end works.

So the “Bytes” part of the input means that is come back in the metadata as Vec<u8>. (The (Vec<DepositId>) is the associated type name.

You didn’t specify a chain or the actual code link, so cannot quite comment further.

The first would indicate (with metadata retrieval) the actual type definition, ie. You can see what is returned and linked (also in the UI). The second will show the actual definition from Rust.

The original definition: https://github.com/darwinia-network/darwinia-2.0/blob/08b703a75e657a120b6701a5781bdbbd88e6a617/pallet/deposit/src/lib.rs#L59

The associated type: https://github.com/darwinia-network/darwinia-2.0/blob/08b703a75e657a120b6701a5781bdbbd88e6a617/pallet/staking/src/lib.rs#L66

And it was used in this storage item: https://github.com/darwinia-network/darwinia-2.0/blob/08b703a75e657a120b6701a5781bdbbd88e6a617/pallet/staking/src/lib.rs#L128

It's a little bit like NegativeImbalance in Substrate. Maybe you are familiar with that.

Which network is this? (You guys have a couple, hence asking - would like to pull the metadata and look at the type definitions in the metadata alongside)

Ok, all good. Cann see the reason from the first link provided.

pub type DepositId = u8;

So it will treat it as the normal Vec<u8> handling in the apps UI, e.g. as a "normal" input type via the Bytes component, aka no individual specification of the items. (In apps UI land all Vec<u8> are handled that way)
