Validate function parameter on range

Hi,

I have

[DataSource.Kind="Test", Publish="Test.Publish"]
shared Test.Contents = Value.ReplaceType(TestImpl, TestType);

TestType = type function (
duration as (type number meta [
DataSource.Path = false,
Type = "Singleton",
MakeResourcePath = () => "TestConnector",
ParseResourcePath = (resource) => { },
Documentation.FieldCaption = "Lookback duration",
Documentation.AllowedValues = { 1..30 },
Documentation.SampleValues = {"25"},
Documentation.FieldDescription = "Defines how many days starting from today the connector will look back in time. It can be maximum 30 days"
]),
environment as (type text meta [
Documentation.FieldCaption = "Environment",
Documentation.AllowedValues = { "Test", "Dev", "Prod" },
Documentation.FieldDescription = "Defines which environment data, do you want access"
]))
as table meta [
// appears in the initial datasource parameter configuration dialog
Documentation.Name = "Test"
];

TestImpl = (DurationValue as number, Environment as text) =>
let

......

 

Is it possible show to user message if value of duration not from 1 to 30...I dont want Documentation.AllowedValues = { 1..30 }, dropdown...I want it be text field. @artemus

No, the most you can do is use Documentation.FieldDescription and Documentation.FieldCaption, and then fail in the TestConnection.
