Called `Result::unwrap()` on an `Err` value: VirtualMachine(...

[NachoPal]

I am getting the following error when I try to deploy latest AssetHub Rococo runtime built from polkadot-sdk master.

panicked at src/task.rs:131:6:
called `Result::unwrap()` on an `Err` value: VirtualMachine(UnresolvedFunctionImport { function: "ext_storage_proof_size_storage_proof_size_version_1", module_name: "env" })

Stack:

try with allow-unresolved-imports. seems like a new host function is added unrecognised by smoldot

[NachoPal]

You mean to add

allow-unresolved-imports: true

in the config.yaml, right?

Unfortunately that didn't work

[ermalkaleci]

Your runtime includes storage_proof_size::HostFunctions. Is this part of standard build?

[ermalkaleci]

@tomaka do we need to implement this on smoldot?

[tomaka]

In principle, no, smoldot doesn't really need a change, and allow_unresolved_functions: true should work. There was a lengthy discussion about this function, and in principle it is used only when parachain blocks are authored or verified by the relay chain. Maybe it would make sense to implement it in smoldot and return an error if the function is called.

[ermalkaleci]

return an error will not help. if allow_unresolved_functions: true didn't help then it's been called

[ermalkaleci]

westend-asset-hub is updated and now won't produce blocks because of this
