String index out of range error hanging server

Hi all.

My Lucee server (version 4.5.1.020) was running fine for a while and then
all of sudden last night it started to throw the following messages and all
requests became slower and slower until they were no longer processed. I
had to restart the server and it appears to be working fine now.

In my logs, I get the following error, repeated several times for the same
exact time, and then same error about 20-30 minutes later (I have scheduled
task running every 2 minutes but not every 20-30 minutes).

I’m using Tuckey rewrite filter, ORM, REST via Taffy.

Any thoughts on what caused the error and why it just randomly began
happening, without any changes to code base?
