Incompatible with Whaleshares

[startailcoon]

I've tried to use BeemPy for interacting with the Whaleshares chain.

Reading data from the chain works on what I've tried, but sending a Transaction seems to be less successfull.

I've tried to run a "witness_update" command, both through CLI and Python, and both end up failing with a Bad Cast(7)

CLI Command: beempy -n https://pubrpc.whaleshares.io

witnessupdate --witness startail --url myurl --signing_key 5xxxxxxxxxxxxxxxxxxxxxxx
