Exception thrown when parsing function when using Let and Distinct commands

[784651]

I have a function that is using logic like this:

.create-or-alter function testfunction() { let temp = random_table_with_timestamp | distinct timestamp=bin(timestamp,1m); temp }

When the application attempts to parse the above command it craps out. Debugging a bit, it appears to be an issue with distinct with a column name assignment and/or the bin() function. Regardless, I can work around this by refactoring my code, but has to download code and test locally before I could figure out what the issue was. If other people try to use this and have similar syntax, it breaks. Yes, there are many ways to re-write this query so that I don't have the assignment or the bin function with distinct.. But if it works in Kusto Explorer and on ADX, I think it should work when being valid when parsing.

Fix is probably going to be an upgrade to the Microsoft.Azure.Kusto.Language package...
