I have a running node without a council configured in genesis. I would like to add a council and initial council members using a runtime upgrade. Is this possible and how would i do it

  • What about calling fn set_members? Apr 14, 2023 at 12:13
  • fn set_memebrs will result in a bad origin error since there are no members completely Apr 14, 2023 at 12:20
  • What did you set as your SetMembersOrigin? Apr 14, 2023 at 12:24
  • Am using polkadot-v0.9.37 and the type SetMembersOrigin is not a member of the trait. But i am updating my code to polkadot-v0.9.40 and i will be able to use it. Apr 14, 2023 at 15:10

This could be achieved by a storage migration (read the linked docs page for details).
