Invalid Secp256k1 pubkey length (compressed): 0

When trying to create a multisig address using https://multisig.confio.run/saga/create :

I get this error message:
Invalid Secp256k1 pubkey length (compressed): 0

Additional browser console output:

If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Both addresses I'm adding to the 2-of-2 multisig were generated using Keplr wallet. Browser is Brave (Chromium-based) for MacOS.

Thank you for the report. The issue is most likely caused by the pubkey not being on the chain (and the error handling failing). Could you try using the My Account page (top right) to see the public keys and construct the multisig with pubkeys instead of addresses?

Improved the multisig creation in #213 and the multisig error handling in #214
