You cannot type function names or their datapack name in /function ín uppercase without getting an unexpected error. If you do
/function kitPVP
// this will happen:
Expected whitespace to end one argument, but found trailing data at position 12: ...nction kit<--[HERE]
// if you do
/function kitpvp:INIT
// it will still throw an error, as INIT is uppercaseHow to reproduce
Write /function
As the first argument, write anything in any uppercase letter, for example /function kitPVP
Watch the error
What I expected to happen
..was that functions inside the /kitPVP datapack would run. Or, that I will get an error telling me to write in lowercase, at least
Uppercase in pack files are not allowed, only lowercase, 0-9 - and _.
It is not unexpected that it treads uppercase as trailing data, but I agree a different error message would be better, but that’s a feature request, not a bug.
