```var descTamanhoId = descTamanho[0].id
var descTamanhoPercent = descTamanho[0].getValue('custrecord_rsc_canal_cliente_desconto')```
Why does it generate this warning?

Property 'id' does not exist in type 'string'.ts (2339)
Property 'getValue' does not exist in type 'string'.ts (2339)

This happens in vscode

it looks like the type system trying to avoid a mistake. it suggests that the type of `descTamanho[0]` is a string, and indeed strings don't have `id` properties.

nor do strings have a `getValue()` method

you should probably share how `descTomanho` gets set

hey <@U5375UUJ2>, `descTamanho` it's set to empty string

ok, in that case the errors you're seeing are not a surprise, except that your array indexing into that variable should cause other errors. Are you sure you don't mean `descTamanho[0] = ''`?

<@U5375UUJ2> I will try to do it that way. This script is not mine, I'm having to fix some bugs. But thanks
