RestEndpoint : conversion error when the parameter type is defined to Int when using POST method

[apetitjean]

Why do I have an error when I force the type of my parameter to Int?
If I remove the type declaration (just "[int]" in the param block) it works without any error.
Problem is : I need to distinguish a string from an int passed to my Rest API. Is that possible?

Here's my server code:

$Endpoint00 = New-UDEndpoint -Url "/test" -Method "POST" -Endpoint {
    param( [Int]$value )

    $value
} 

Client call:

PS C:\> Invoke-RestMethod -Uri 'http://localhost:3000/api/test' -Method POST -Body {value=2}

error
-----
@{message=Cannot process argument transformation on parameter 'value'. Cannot convert the "2" value of type "Microsoft.Extensions.Primitives.StringValues" t...

Error log :

If I remove the type declaration it works as expected.
As I always oblige myself to declare types when I know them, is it bad to do that in the context of a Rest API?

Here is what I get without declaring any type in the param block of my Endpoint:

PS C:\> $i = Invoke-RestMethod -Uri 'http://localhost:3000/api/test' -Method POST -Body {value=2}
PS C:\> $i.gettype()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     Int64                                    System.ValueType


PS C:\> $i = Invoke-RestMethod -Uri 'http://localhost:3000/api/test' -Method POST -Body {value='2'}
PS C:\> $i.gettype()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     String                                   System.Object

Interesting! I haven't run into this before. It seems like it should be fixed though. I don't see why you could specify typed values.

Why I could or why I couldn't? 2018-04-25 19:37 GMT+02:00 Adam Driscoll <notifications@github.com>:

@apetitjean That was a typo: couldn't!

I think it should work the way you suggest.

Fixed in 1.6.2.
