After Effects TypeScript error when using setValue() | TypeScript Community | Page 1

TypeScript throws an error when I try to set a property value of a text layer:

newTextLayer.property("Position").setValue([0,0]);```

TypeScript throws the following error:
Property 'setValue' does not exist on type '_PropertyClasses'.
Property 'setValue' does not exist on type 'PropertyGroup'.
 
Is there a better way to set properties on text layers?

#

property("Position") returns a _PropertyClasses
_PropertyClasses is an alias for Property | PropertyGroup | MaskPropertyGroup
https://github.com/aenhancers/Types-for-Adobe/blob/master/AfterEffects/22.0/index.d.ts#L690

however,
setValue only exists on type Property
it does not exist on type PropertyGroup or MaskPropertyGroup

make sure the result from property("Position") is a Property and not one of the other two possibilities
then yoll ba able to call the setValue method on it
