Side note: Robert's PR (#7447) replaces the pubkey field with the JSON representation of the multisig pubkey, which includes pubkeys and threshold. But that's on master (and 0.43+) only.

So this issue indeed needs a separate fix.

I double checked with @atheeshp, he will create a PR directly on release/v0.42.x since this is fixed on master via #7447

Addressed this in #9108
