The S030 analyzer reports cases of schemas which enables only Computed and configures InputDefault, which is not valid.

&schema.Schema{
    Computed:     true,
    InputDefault: "example",
}

&schema.Schema{
    Computed: true,
}

Singular reports can be ignored by adding the a //lintignore:S030 Go code comment at the end of the offending line or on the line immediately proceding, e.g.

//lintignore:S030
&schema.Schema{
    Computed:     true,
    InputDefault: "example",
}
