Hey! When broadcasting a staking (pool nomination) tx for Kusama using the following code, The library throws an exception:

apiPromiseClient.rpc.author.submitExtrinsic(serializedTx)

The exception is:

error: findMetaCall: Unable to find Call with index [41, 0]/[41,0]

It is worth mentioning that this script works fine with Polkadot and Westend however when trying on Kusama I get the error above.

The issue was fixed by using the correct RPC, where I was still using DOT RPC in some parts of my script instead of the KSM RPC.
