StringIndexOutOfBoundsException (no CodeWhisperer)

[socketbox]

Describe the bug Without CodeWhisperer enabled, but with the AWS Toolkit installed, I receive the following exception:

To reproduce Can't really say when this first appeared, as the blinking red "IDE Internal Errors" button is at the edge of my vision, so I don't know what might have triggered it, though I was in a Markdown document at the time (when I noticed it).

Expected behavior No exceptions from this plugin.

Hi @socketbox , could you upgrade your AWS Toolkit for JetBrains to v2.1+ and see if this happens again? Thank you!
