This error you get when trying to bond KSM on Kusama using https://polkadot.js.org/apps/#/staking/actions with the default Kusama nodes hosted by Parity.

I noticed the password field is missing, that might be the issue? How to sign the transaction without unlocking the account?
:wave:
Also happens on "set session key" and "start validating"
Apparently, it's random and it seems to work in 1 out of 10 tries.
Win 10.1903, Opera 63.0.3368.53
Same problem.
Something has gone seriously wrong with a merge - tracking it.
Sorry about this, something went seriously wrong in the deps - and generally they are not as impactful (Sadly I screwed up the testing an only e2e tested with the extension in this case.)
As of now the update has been merged and available on https://polkadot.js.org/apps/#/staking/actions
... passwords are properly prompted for again.
