     A: When specifying your own state query, you must provide the return type of the state you're trying to retrieve. This is because the api-client only gets bytes from the node and must be able to deserialize these properly. That is not possible without knowing the type to decode to. This type may be for example a simple `u64` for retrieving the `Balance` of an account. But careful: If you're looking at the pallet code and its return type, don't forget to take the Query type into consideration. The `OptionQuery` for example automatically wraps the return type into an `Option` (see the [substrate docs "Handling query return values"](https://docs.substrate.io/build/runtime-storage/) for more information). Alternatively, you can always double check via [polkadot.js](https://polkadot.js.org/).
 	If you're importing a value directly from the runtime, as it's done in this [example](https://github.com/scs/substrate-api-client/blob/fb108a7d1994705bbca50233e3bc66cec3726523/examples/examples/subscribe_events.rs#L25-L27), remember to adapt it to the node you are querying from.

+4. Q: I get a compilation error when compiling for `no-std` or `wasm`. For example "unresolved import `sp_core::storage::Storage`" in `sp-state-machine`. What is wrong?
+
+    A: You might have to specify `RUSTFLAGS` for compilation. See the [substrate documentation](https://github.com/paritytech/polkadot-sdk?tab=readme-ov-file#wasm). If you still get an error like `error[E0308]: mismatched types` in `sp-io` you might have to switch to the `master` branch (instead of using a release branch). This is a temporary issue do to incompatible versions being published on crates.io and should be fixed in the future.
