What happened?

Log output

Error: invalid configuration: processors::transform: undefined function limit
2023/05/15 09:50:09 collector server run finished with error: invalid configuration: processors::transform: undefined function limit

Additional context

I think this is because #18822 accidentally set the factory name to uppercase, but functions in OTTL have to be lowercase. See:

opentelemetry-collector-contrib/pkg/ottl/ottlfuncs/func_limit.go

Line 33 in d67cbca

return ottl.NewFactory("Limit", &LimitArguments[K]{}, createLimitFunction[K])

.
