Variable: "Property is not allowed"

Hello, hopefully a simple question. In the ‘Variables’ (bottom box) of any query, I get “Property X is not allowed” no matter how I attempt to name it. For example below, I will get brown line under ‘where’ saying ‘property where is not allowed, no quick fixes available’. Same for ‘property options is not allowed, no quick fixes available’. It seems to be independent of upper query, and independent of the variable name. Does anybody have any suggestions? Thank you very much!

{
“where”: {
“vendor”: “Shopify”
},
“options”: {
“limit”: 2
}
}
