Render service returning [cltokxyzkdtnhgnsbdfcltok1]

Strange error that just started happening on the latest OD development driver within the last 3-7 days.

I am not sure what else it impacts, but at least the SOAP render service returns incorrect data for content inside of some macros (like noformat) that looks like:

[{ xxxxxx }]

Removing any of the square or curly brackets works fine. The data returned is always the same no matter what is inside the brackets:
[cltokxyzkdtnhgnsbdfcltok1]

Here is a specific re-create using Confluence CLI.

java -jar /sde/atlassian-cli-4.0.0/lib/confluence-cli-4.0.0.jar --action render --space "ds"  --title @home --content "{noformat} [{ xxxxx }] {noformat}" --clean --server https://bobswift-test.jira-dev.com/wiki --user automation --password "xxx"
Rendered data
<div id="ConfluenceContent"><div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent">
<pre> [cltokxyzkdtnhgnsbdfcltok1] </pre>
</div></div></div>

I forgot to mention, this is a very often found text when dealing with JSON.
