Error signing session.setKeys in polkadot JS. #207

Closed redref closed 3 months ago

redref commented 5 months ago

Hello,

Detected an issue with Kusama session.setKeys call.

Error JS side :

signAndSend: error: Error: Unexpected buffer end

My understanding is that this issue is linked to drop of imonline key in the extrinsinc call. Encoded call data :

I guess an update is needed in key reading methods here

Thanks for any tip.
