I receive an internal error TypeError(func=:OneTo, context="T", expected=T<:Integer, got=Float64) when running some of my code. It does not appear to prevent execution of code, but does seem to slow it down a bit and prints a stack trace before code starts executing.

This may be related to #39082, but that was found in 1.7 whereas this issue is on 1.6.3.

So to be clear, this is fixed on 1.7 and we just need to find what to backport to 1.6?

I don't know for sure if it's the same issue, and I have not tested it on 1.7, however the report looks very similar except for the difference in types reported.
