Hi @fauxbytes - thanks for reaching out.

While researching, I came across this similar issue where the service team confirmed that this's expected behavior as mentioned in the docs like follows:

If you specify logGroupNamePattern in your request, then only arn, creationTime, and logGroupName are included in the response.

Hope that helps and please let me know if you have further questions!

Thanks @aBurmeseDev.
That does clarify it. Appreciate you looking into it and finding an aswer for me.

In the context of user feedback (merely my opinion here): to me, logGroupNamePattern & logGroupNamePrefix look like they do quite the same thing: they are filter flags: One searches by prefix. The other - by substring. In that sense, I don't see the rationale of those returning different output. If there is one, I'd be keen to understand it. If there isn't, that's fine too, but I wouldn't call it 'expected behavior'.
