Description:
Fixed the Log group ARN parsing logic to account for another, valid log group ARN representation that includes a trailing
:*
on the ARN. Before this fix, the parser would incorrectly pick up the asterisk as the log group name.Before, we used
bytes
for performance, but now that we're actually returning what we callSplit
on, I think it makes more sense to usestrings
instead.Link to tracking Issue:
fixes #13702
