Validation not done on values which are zero

[vancejc-mt]

Hello,

Running apollo-server 3.8.2 using this package, l have the following in the schema:

extend type Query {
    searchForFonts(
        pageSize: Int @constraint(min: 1, max: 25)
    ): FontSearchResponse!
}

If I send a pageSize value of -1 I correctly get an error of it being below the minimum. However, if I pass a pageSize of 0, it doesn't flag an error at all.

I suspect possibly this is an issue with apollo-server (where he won't call parseValue at all because of a stray if(value) check) but wanted to check and see if anyone had run into this before?

Thanks

Have you tried to make pageSize mandatory, or maybe set the default value for it as a workaround? This definitely looks like it treats 0 as a not set value at all 😕
