Hey @q9f I been checking the CI errors and I found this:

The spec is invalid, you have to execute this command to generate the right westend-dev-spec.json. More details here :

gossamer import-runtime --chain chain/westend/genesis.json --wasm-file westend_runtime.compact.compressed.wasm > chain/westend-dev/westend-dev-spec.json

I've been trying that and I found an issue executing that command, we can bypass the issue adding the following lines here :

chainSpec.Genesis.Runtime = &genesis.Runtime{
   System: &genesis.System{},
}

Even using the right spec I'm having this error now:

creating new runtime instance: \"ext_crypto_ecdsa_generate_version_1\" is not exported in module

I think we have to add all missing runtime exports in our test runtime here

I opened this quick PR to solve that issue

Thanks for the comments. I'll try to properly generate the chain specs again.
