Backport of #24498 to 22.x branch
This was already backported to the 23.x branch in #24511, but vasild discovered the issue can affect 22.x as well #15936 (comment):
It's not very important to backport this to 22.x because I can work around the issue other ways, but I do see 22.x is listed as an active branch https://github.com/bitcoin/bitcoin/branches, so if there is another 22.x release, it would be nice to have this fix and not have a wonky uncaught univalue exception waiting to be hit
