Midnight Glacier claim on Cardano issue raw signing

Alright I’m about to give up. I have full set up the AWS system for raw signing on Cardano and can’t get the final claim button on the midnight glacier claim to go through. I’m using the Fireblocks python SDK for signatures. I’m not sure if the midnight claim system requires the “Stake public key” for signing or not, but the only public key I can obtain from Fireblocks is the payment public key. Even if I try to use the derivation path of the staking, fireblocks only returns the public key of the payment address.

When I go to claim for an address, I input the public key and the COSE_sign1 signature and the portal ACCEPTS the signature as valid. But when I click the “Complete Claim” button it gives an error message (image).

  1. Wish I could find definitive info on which public key is supposed to be used for signing

  2. If it is the stake public key, why can’t I obtain from Fireblocks.
