Tooltip error when using .create-or-alter: Cannot read properties of undefined (reading: 'IsOptional')

[johndog]

With the following code, hovering over any keyword results in a tooltip Cannot read properties of undefined (reading: 'IsOptional')

.create-or-alter function 
BytesInMB(bytes: long) {
   round(bytes / 1024.0 / 1024.0, 2)
}

It doesn't seem to matter what's in the function body. In fact, it seems to happen with any dot commands (e.g. .show table).

Changing the function above to use let BytesInMB=() syntax, the tooltips work correctly.

It also reproduces with the example at https://github.com/rosshamish/kuskus/blob/master/kusto-syntax-highlighting/test/snapshots/create-or-alter-function/create-or-alter-function.csl.

Syntax coloring works, tooltips don't (for me).

hi @johndog , thanks for the report. I'm not actively maintaining this extension anymore but I'm open to facilitating contributions. I see a similar report at #102 , probably related.
