[register-finality-provider fail] failed to register the finality-provider to Babylon. The provided serialized extended key length is invalid

Hi team,

we are trying to register the finality provider, while it outputs as below:

$ fpcli register-finality-provider \
> --btc-pk ea8ad7c3ece800b16238ffb886b226a738c44b3cafbe12e990f967f1a2f477a4

[fpd] rpc error: code = Unknown desc = failed to register the finality-provider to Babylon: rpc error: code = Unknown desc = rpc error: code = Unknown desc = failed to execute message; message index: 0: rpc error: code = InvalidArgument desc = the provided serialized extended key length is invalid [cosmos/[email protected]/baseapp/baseapp.go:991] with gas used: '50088': unknown request

We've already added the wallet key and get funded as well. Could you please take a look ?

Are you trying to register it to Babylon testnet3? If so, sorry, it is already sunset.

curious if this is a formatting issue as i see some weird character ">" in the cmd, does
fpcli rfp --btc-pk ea8ad7c3ece800b16238ffb886b226a738c44b3cafbe12e990f967f1a2f477a4
also return the same error?

Hi @gusin13, it's still the same result. ">" is just showing it's another line.

And we've tried fpcli rfp --btc-pk ea8ad7c3ece800b16238ffb886b226a738c44b3cafbe12e990f967f1a2f477a4, while output same error message.
From the error message, I can only tell it might relate with RPC to babylon endpoint.

Could you please take a look again ? And please let us know if we can provide more details to your side, thanks !
