I still see this issue in Version: 0.10.143.381 PyCharm 2018.2 (Community Edition) Build #PC-182.3684.100, built on July 24, 2018 JRE: 1.8.0_152-release-1248-b8 amd64 JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o Windows 10 10.0

Any workarounds or updates on this issue.....

I have seen this several times today in the PyCharm editor while entering my test code. I had a typo in the code and it triggered this exception.

Intellibot Version: v0.10.143.381 PyCharm Version: 2018.3 build #PC-183.4284.139 JRE: 1.8.0_152-release-1343-b15 amd64 JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o

I was adding a variable in the Variables section near the top of the file and I entered ${ and paused. Everything from the beginning of the line to a matching } in a Keyword definition was highlighted. It turns out that I missed the open { in that line and that caused the Exception to be thrown.

I fixed my code and the Exception was easily cleared.
