Error when running /consumersettings

Context

Integration with Learnosity stopped working after a deploy on July 3rd. Opening devtools, I found that the issue happens on a POST call to https://authorapi.learnosity.com/v2021.3.LTS/consumersettings, which responds with the error message: Invalid authentication parameter length. Check the following parameter(s): consumer_key, timestamp, signature

Comparing the failing environment with a deploy that happened last week, there is indeed a change in the size of signature, from 64 to 68.

Looking at recent commits to master, this one adds a prefix $02$ to the signature, so it could be causing an issue down the line when another bit of code expects the signature to be of size 64.
